Next, Mu Qingli did not stay in Pingcheng as expected, but stayed for four months.

Outside Pingcheng, Mu Qingli and Zhang Xianmin set up a small experimental field dedicated to experimenting with corn and potatoes.

During the experiment, Mu Qingli found that things were far from being as simple as she thought, and just how to prevent insects and rats gave her a headache for a long time. In the previous life, all kinds of insect repellent rat poison were varied, and the effect was wonderful, unlike here, which could only be simply pounded into potion with irritating plants and used for watering, the control effect was too weak, and the first batch of experimental fields was killed by one-third of the seeds.

Mu Qingli had to rack his brains, desperately trying to recall what effective treatment methods there were, and in the end, he only came up with a lime.

Lime disinfection and insect control effect is very good, but also can neutralize the ability of soil, is a very strong fertilizer.

Now that you know the lime, the next step is to refine it. Mu Qingli tried hard to recall the small lime factory on the edge of her grandmother's village, and the scene she saw when she sneaked in: first there were kilns burning fire, which were very large, and then there was a pile of gray stones on the ground, and the workers used shovels to shovel the stones into the kiln, she recognized those stones, which were very common on the mountain, and then they were gone.

Mu Qingli has a headache, how long does it take to burn? How to burn? She didn't know what to do with it after it was burned.

Mu Qingli gritted her teeth and comforted herself: Any great invention must be the first step to take, plus the ninety-nine steps of failure, to succeed!

So, Mu Qingli groped for refining, and after half a month, he finally refined the lime!

With lime, the seeds of the second batch of experimental fields were almost free of insect pests and rat bites, and because of the application of lime, the land was fertile, and the second batch grew faster than the first, and the spirit really surprised the two good farmers.

The problem of sowing seeds in the first step was solved, and Mu Qingli still had to worry about the season of seed sowing, because there were few seeds for experiments, so Mu Qingli could be very relieved to plant boldly, but if you want to plant on a large scale in the later stage, the season is very important.

If she remembers correctly, in previous years, her grandmother's potatoes were planted in two seasons, the first season of spring potatoes (potatoes also known as potatoes), which were planted and sown in February and March, and harvested in May and June; The second season of autumn potatoes is sown in September and harvested in December. The potatoes of Mu Qingli's experiments are exactly the wave of autumn potatoes.

And corn is out of season. Spring maize is sown in late April and early May, and can be harvested in late August; Autumn maize should be sown no later than mid-July and harvested in mid-to-late October.

Because of this, Mu Qingli didn't dare to take all the corn seeds for experiments, but kept half of them.

Mu Qingli did not reserve, and taught all the agricultural knowledge she had learned in her previous life to the two good farmers Zhang Xianmin found, while teaching, she sighed, this should be the most leisurely time for her to come to this other world, every day only to worry about the small experimental field, shuttling through the field every day. It made her feel like she was back in her childhood, and she was so satisfied when she followed her grandfather and grandmother to work in the fields.

Those two good farmers are both in their forties, and they have been digging in the field for most of their lives, and this time they followed Mu Qingli to tinker with the experimental field, and they admired it more and more. Mu Qingli can always teach them different things, and put forward some just right ideas to solve the places they have been puzzled about, especially lime, which greatly refreshed their cognition, with this fertilizer that is powerful and insecticidal, the harvest can at least double!
