Sunflowers have well-developed root systems and penetrate deep into the soil, which can absorb and utilize water in deep soils. The fibers in the stalk are sponge-like, which can also store more water. At the same time, the stems of sunflowers are densely covered with bristles and have a waxy layer on the leaves, which can reduce the transpiration of water.

As a result, sunflowers are very drought-tolerant and can still grow normally in an environment where the average soil moisture content is less than 20%. From seed germination to plant growth, it does not need much water, which is conducive to squatting.

However, sunflowers require a lot of water during the growth cycle from the first bud to the flowering and fruiting. If the water required during this period cannot be satisfied, it will directly affect the yield of sunflower seeds.

Therefore, when the buds were found, Peipei immediately started irrigation as planned. Irrigation of sunflower fields requires a long stream of water to ensure irrigation and prevent lodging.

At the same time, the tender branches in the axils of those leaves were removed one by one by Liang Yue and the others. These branches consume nutrients and have a great impact on the yield and quality of sunflower seeds, so it is necessary to see one and knock out the other, and the sooner they are knocked out, the better.

When the sunflowers bloom in small pots, the Gangu rain stops the growth of all things. In a dense and lush foliage, the flower plates look so brilliant and dazzling, decorating the whole sunflower field beautifully.

"It's so beautiful to have such a big flower!" Pei Pei couldn't help but admire when he looked at it.

Don Nuo wiped a handful of beads of sweat from his forehead and came out of the forest, and he couldn't help but lose his mind for a moment when he saw this scene. Seeing this, Gangu Yu smiled and said, "Beautiful, right? This is an edible sunflower, in fact, there is also an ornamental sunflower, the plant is smaller, and it can be planted in a flower pot for ornamentation." ”

Tang Nuo shook his head: "The little flower in the pot, how can there be such an atmosphere. ”

"I like this sunflower too. Pei Pei licked his lips and agreed. "It's a pity that I don't have a blank water reflection stone on my body, otherwise I would have to leave some images as a souvenir. ”

Gangu Yu smiled and took out a piece of water reflection stone: "Brother knows that you will definitely have this appeal, and I have prepared it for you." ”

Pei Pei was overjoyed, and immediately ran to the side of a sunflower and urged, "Hurry up." Bring me one first!"

Gangu Yu smiled dumbly: "Yes, but you better put down the scissor hands first." ”

After the women of Liangyue rushed back, Gangu Yu took a group photo for everyone in the sunflower field, and rested for a while before starting the next work.

Sunflowers have a very low self-flowering seed setting rate and require cross-pollination. Sunflower is an insect flower, and Gangu Yu did not dare to rashly invite Yin Yimo, Xiao Xiao and others to use wind power to pollinate. At the same time, there are no bees to pollinate in this winter greenhouse, so artificial pollination has become a huge and complicated project.

Gangu Yu directly distributed a pair of cotton gloves to everyone. Everyone put on their gloves and started pollination.

During pollination, everyone followed Gangu Yu's demonstration, holding the neck of the sunflower flower plate with one hand, and gently touching the flower plate with the other gloved hand to make the pollen grains stick to the glove, and then gently touching the other flower plate in the same way and rubbing it down in turn.

Because the florets in the sunflower tray bloom sequentially from the outside to the inside, you need to be careful when pollinating. Fresh pollen is applied to the flowering florets so that more plants are pollinated. The more pollen mixed on the gloves, the better the pollination will be.

However, when pollinating, Gangu Yu couldn't help but be teased by everyone.

At this time, the sunflower plants were more than two meters high, and Gangu Yu, who was twenty-two years old, would encounter the embarrassing situation of standing on tiptoe and not reaching the flower plate from time to time, so he had to learn from Liangyue and others. Summon a demon vine to lift yourself up.

"Mother Nature is really harsh on you......" Pei Pei, who was entangled in the demon vine summoned by the cold moon, couldn't help but cover his mouth and chuckle when he saw this scene.

"This is called condensation is the essence!" Gan Guyu glared at her, and then pointed to Tang Nuo, who was also being held up by his own magic vine beside him, and argued, "Don't you see that Arnold can't reach it?"

“...... I turned the year 16 years old. Arnold couldn't help but mutter.

Only then did Gangu Yu realize that he had not found the right reference. I had to cough dryly, and said slowly: "I think before I came to the Forest of Nature, the Mother of Nature asked me if I wanted a great body or a strong brain - I chose the latter. ”

"Powerful brains?" Liang Yue chuckled, "How dare you say it." ”

"Actually, when you came to the Forest of Nature, Mother Nature also asked you. Gangu Yumian said nonsense without blushing and heartbeat, "It's a pity that you all chose the former between peerless looks and smart brains, so I don't remember." ”

Pei Pei was stunned, and suddenly looked at Liang Yue suspiciously: "Is this guy praising us for being beautiful?"

The women were silent for a while, and Liang Yue twisted for a long time with a strange expression, and suddenly held back a sentence: "Why do I suddenly think that what Xiao Guyu said may not be completely true?"

Gangu Yu almost didn't hold back her internal injuries, as long as Pei Pei encountered a topic related to appearance, she immediately became stupid and cute.

The first artificial pollination was done in a joking room. During this period, Gangu Yu involuntarily hummed a children's rhyme in Chinese: "I have a beautiful wish to sow the sun when I grow up." It is enough to sow one by one, and it will produce many, many suns......"

"What kind of song? I don't understand it, but the rhythm is pretty bright. Pei Peiqi said.

"Sounds good, right?" said Gangu Yu.

Pei Pei nodded reluctantly: "If it was Lin Lin singing, it should sound better...... But I always feel that this shouldn't be a song for your age......"

“......”

Some of the injured Gangu Rain stood on the edge of the field again, took out a Ten Thousand Things Growth Scroll to activate, and continued to slowly start to give birth. At the same time, others need to quickly complete the second and third artificial pollination of the sunflowers.

Deliberately controlling the efficiency of production like this is actually a test of the magician's control over magic. Gangu Yu rarely practiced magic deliberately, mainly relying on his talent and perception when controlling the growth of all things. As time passed, a layer of sweat also covered Ganguyu's forehead.

The rest of the people also knew the load of Gangu rain at this time, so they deliberately accelerated their speed. With the experience of the first pollination, everyone gradually became more familiar with the pollination, and the subsequent pollination work was quickly completed.

Soon after, the bright yellow petals on the outer edge of the sunflower disc gradually withered, and the sunflower seeds gradually appeared from the outside to the inside, marking the maturity of the seeds. The rain stopped all things and sat down on the spot to rest.

"I finally know now how hard those little flying insects are pollinating and collecting honey. Pei Pei wiped a handful of sweat beads, got out of the sunflower field and complained, "It's better to have tomatoes, and you don't need to pollinate them by hand like this." ”

"In fact, the crops in the greenhouse can be supplemented by artificial pollination to increase yields. Ganguyu smiled faintly, "It's just that tomatoes are self-pollinating plants, and the ones that my brother has taken out are also excellent varieties with a high fruit setting rate, so I don't have to worry about pollination."
