The camp has been too busy, and Jin Jing can't go to class normally. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 The teachers discussed that the course could only return to normal after the wheat harvest.

In late July, it is the rainy season. Jin Jing was assigned an important job, picking blueberries.

This perennial shrub is common in the Xiaoxing'an Mountains forest area, and its roots are rooted in the permafrost and the fruit ripens in late July and early August every year.

The little berries have a pleasant blue skin covered with a layer of white powder.

At first, Lin Qian noticed that there were many of these wild fruits in the groves of the wasteland, and she mentioned them at the morning meeting. Wu Rui arranged for Lin Qian and Jin Jing to pick specially.

Blueberries are sweet and sour, fragrant and pleasant, but they are not easy to pick.

In order to protect against mosquitoes, they wrap their bodies tightly. After entering the woods, light a pile of smoke to collect with peace of mind.

It is necessary not only to guard against the presence of wild wolves, but also to carefully examine the feet. Blueberries prefer damp and shady, and need to be pushed away from the low branches and leaves of the bushes to find the few sparse fruits.

Even so, the two were able to fill several baskets every day.

Wild blueberries are slightly sour, similar to mulberries, and turn purple on the tongue when eaten. Picking up a handful of berries and throwing one into your mouth from time to time stimulates each palate, which is not only a great pastime, but also helps to combat fatigue and relax the nerves.

The blueberry picking season lasts for a month, and although everyone eats a lot, they still store a lot of it for vitamin supplementation in winter.

In order to facilitate preservation, Lin Qian wanted to pickle the blueberries, but Bu Yiren proposed to simply make wine.

This is not a cranky idea, blueberries are not low in alcohol, and people will be slightly drunk if they eat too much. Jin Jing had a big burst of luck and picked up a drunken roe deer, with purple lips. She and Lin Qian directly carried the roe deer back to the camp and opened meat for everyone.

Liquor production is handled by one person. She has a lot of experience in making a variety of fruit wines at home. However, the conditions in the wasteland are limited, so we can only do our best.

She first made koji by adding flour and water, making bricks, cultivating microorganisms, and making her own koji. and put half of the blueberries in a birch bark bucket, sealed it with a lid, shook and smashed it, and brewed it into the original juice; It is then sealed and fermented, and after two months the blueberry wine is ready.

The blueberry harvest had to be stopped halfway through, and only six jars were made, because the most important time of the year had arrived.

Wheat harvest!

The combine cultivator has no harvesting components, and the wheat is harvested by manpower.

There are only five scythes. According to Cao Dong's experience, a skilled farmer can harvest one acre of wheat a day. In other words, if you harvest 200 acres of land with five sickles alone, it will take forty days.

This is certainly unacceptable.

Therefore, the "human harvester" project team led by Luo Shili and Mao Zhigang started research and development early.

They dismantled some of the tractor's wheels, transmission wheels, gears, transmission belts, small pieces of barbed wire, and knives from the combine cultivator as parts, and soon built the first machine - scissors!

The scissor type is a "manpower hand propellation harvester". It is composed of a fuselage, a push handle, a driving wheel, a driven wheel, a transmission shaft, a moving blade, and a static blade.

The moving blade is linked with the driving wheel, and the static blade is sheared to form a harvesting assembly.

Mao Zhigang mowed the grass and found that the harvesting of this thing is much faster than that of the sickle, the effort is also saving, and the overall size is compact, which is more suitable.

But Luo Shili was very dissatisfied, thinking that it was too simple, not only was it laborious to promote, but the wheat cut was also disorganized, and it needed to be put together.

The No. 2 "turntable type" was successfully developed a few days later.

The "Rotary Manual Harvester" consists of a rack disc, an iron bar frame and a toothed bevel disc knife. The person pushes the machine, and the disc knife is blocked and rotates to cut.

Its cutting efficiency has been greatly improved, and it is expected to be 1.5 acres per hour. Chairman Wu Rui is quite satisfied with this, but Luo Shili still has some ideas and hopes to continue to make substantial improvements.

As a result, the No. 3 "foot pedal" was grandly introduced.

"Foot pedal human harvester" is powered by human gravity, when people are walking, they step on the pedal rings on both sides alternately, pull the chain to drive the coaxial sprocket to rotate, accelerate through the transmission mechanism, and the inertia flywheel rotates at high speed to store energy, and then the power is transmitted to the disc cutter of the actuator to complete the action of reciprocating cutting and unloading.

The concept of this machine is quite advanced and the construction is complex. Jin Tong looked left and right and failed to understand the design idea.

Luo Shili was assembled and was full of spirit, believing that the No. 3 machine had reached the peak of artificial power efficiency. What he is even more proud of is the automatic alignment function of the wheat straw after harvesting, which can be described as a leap forward.

In the subsequent mowing experiment, due to the instability of the overall structure, the No. 3 machine was crushed by Luo Shili's own gravity and became a part all over the ground.

The experiment failed!

The No. 3 machine is all up to Luo Shili, because the others are busy building the No. 4 machine.

Conceived by Mao Zhigang, designed with the assistance of He Gongda, and manufactured by others, the No. 4 machine "Ten Thousand Arrows" has a long name - "Arrow Row Hook Saw Blade Sawing Machine Surface Harvesting Wheat Straw Manual Harvester".

A sawing hook is placed at the mouth of the machine, a sharp saw blade is worn inside the hook, and there is a row of arrows at the bottom of the sawing hook that can go back and forth. In addition, a rectangular sliding straw attachment frame is hung horizontally on the left and right sides of the fence, which also ensures self-harvesting after harvesting.

Everything is fine with the No. 4 machine, but the efficiency is too slow, which is the same as the No. 1 machine, and it is estimated that it takes two hours to complete the harvest of one acre of land.

After a not heated discussion, Luo Shili admitted that his thinking was wrong, and he turned around and installed automatic loading and assembly parts on the No. 1 and No. 2 machines respectively; The No. 3 machine was also reassembled, but modified to an ordinary push type, which can harvest 2 acres per hour due to the efficient transmission.

Due to material constraints, it was not possible to make more. So far, the total harvesting efficiency of the pioneers has reached 5 acres per hour. It takes 40 hours to harvest 200 acres of wheat.

Before the harvest, the construction of the camp was also completed, and the dormitory was completed.

The dormitory is opposite the cafeteria, and is two brick houses side by side, of average size, one for boys and one for girls.

There are only 7 girls left, and there is only one bunk in the dormitory, which is not only set up with a fire kang, but also a fire wall. Designer Chen Zhenxiu called it: a fire wall type ondol.

The test burning found that the smoke flowed in the wall, and the heating effect was very obvious, and the warmth retention ability was greatly improved. Not long after the fire wall was burned, the people in the house were sweating.

There are many men, and the dormitory has two rows of bunks opposite each other, and the same independent heating system. It's summer, though, so you don't need to use it.

The dormitory was completed on August 1. The next day, before they had time to rest, they entered a busy harvest season.

In August, the sun rises early.

Work starts at four o'clock, the sun sets at seven o'clock in the evening, and there are 13 hours to work.

Chairman Wu hopes to speed up the process and strive for the completion of the project in three days.

Four manpower harvesters, five sickles, and nine people operate at the same time. There was also someone behind the reapers who was responsible for bundling the wheat, so almost all the members of the camp were in battle, including Martin and Yuan Wending, and no one could be lazy.

Even if you don't go to the field, such as Jin Jing, it is also used as a logistical support, cooking and delivering water to others.

Whether it is pushing a machine, wielding a sickle, or baling wheat, it is rotated every four hours, after all, some work is easy, and some are physically demanding.

It rained for half of July, but it was sunny in early August, and there was still a lot of water in the ground.

Although the manual harvester was designed with muddy conditions in mind, it was still not well prepared, and it was often stuck, trapped, and even needed emergency repairs. Fortunately, the IQ of this group of people is not low, and a simple fiddling can solve the problem.

The people in Shimoda are anti-mosquitoes, and they are all long clothes and trousers, mosquito-proof hats, scarves, and gloves. Some people thought that the hat was in the way, so they simply covered their head and neck with clothes, revealing only their two eyes.

The wheat field is slippery, and people walk in it, one foot deep and one foot shallow, and the shoes and socks, and even the lower half of the pants are quickly soaked, which is very uncomfortable.

When using a sickle, it is common to cut the hand, and they bandage it casually and get on with the work.

When the wheat was bundled, although the arms were still burned by the wheat through the clothes, no one complained.

The golden wheat fields are only 200 acres, but they are vast and seem to have no end in sight.

The shiny knife saw knocks down the wheat piece by piece, and when the straw is cut, it makes a "sizzle" sound.

Jin Tong likes those sounds, which are nature's reward for the hard work of laborers, and they are more beautiful music than any praise.

After cutting a ridge of wheat, drinking a bowl of cold white open handed by his sister, wiping his sweat and beating his waist, and then returning to the field, his fingertips caressing the heavy ears of wheat, his heart was only satisfied.

The 70 acres with the most fertilization, the best growth, and the fullest grains are seed fields, which are prioritized for individual harvesting. In the plan, next year's cultivation area will be doubled, and 45 catties of seeds are needed per acre, and 9 tons of seeds must be retained for 400 acres.

After cutting the seed field, cut the ration field. Three days of intense labor honed everyone and made them tired. When the harvest was completed as scheduled, Jin Tong hated to sleep for a day and a night.

But laxity is not allowed, and they must tense their nerves and seize the time on the rare good days, because the farming has only just begun.

After the harvest was completed, the girls picked up the ears of wheat in the wheat field, striving for "grain return to the warehouse", and Jin Jing also joined the ranks of picking up ears of wheat.

Jin Tong touched the scene and sang a famous children's song:

The little girl who gleaned ears of wheat walked barefoot on the ridge.

A wild chrysanthemum is inserted on his head, and a small bamboo basket is held on his arm.

The mountain song is long, ah, the pigtails are shaking, and the little girl comes,

……

"I'm wearing shoes, okay?"

"No wild chrysanthemums!"

"A ponytail is not a pigtail!" Jin Jing kept protesting.

……

Although this year's harvest is bumper, she does not lose a grain of grain,

The little hand picked up the golden ears of wheat, and the dimples were full of laughing waves.

The autumn wind is long, and the ears of wheat are swaying. Happy little girl

……

"What dimples laugh profusely!" Jin Jing was so angry that she threw down the basket and rushed over to pinch the soft flesh on her brother's waist, "Is Jin Tong a brother like you?" ”

"That's it," Lin Qian was also dissatisfied, "how can you say this about your sister!" ”

"Here's the lyrics, that's what it says!" Jin Tong struggled to defend himself.

"What the original text, isn't it what you wrote!" Lin Qianqi said.

"That's it! It's so badly written, I'm going to change it! Jin Jing had Lin Qian's support, and immediately crossed her waist with her hands, commanding her spirit.

"What to change, I can't sing in the future!" Jin Tong faced two beauties, one big and one small, and fled without a fight.
