"Those who plant something else on the ground from time to time don't have that." Quiet continued. "Therefore, I think it is better to not crop continuously on a piece of land, but to rotate crops."

"Crop rotation should be able to achieve the purpose of combining land use and land cultivation, and crop rotation should also really be able to control diseases, insects and weeds. Rotations are really much better than combos.

Afraid that Emperor Xiyun would not understand, he explained quietly: "Continuous cropping is to always plant the same crop on the same land, and crop rotation is to plant different crops in turn on the same land. ”

"Continuous crop rotation" Emperor Xiyun frowned, kept muttering these words, for a long time, he couldn't help but be overjoyed, and praised: "Quiet talent, immeasurable!" Thank you, Father-in-law! ”

Quiet smiled: "Father-in-law doesn't need to thank us, we are a family, we can help my father-in-law and Chengyu, do something for my father-in-law and Chengyu, and benefit the people of Xiyun, we are also happy in our hearts." ”

It's us, not me, obviously, quietness brought Xiao Changyi, the father-in-law.

Xiao Changyi listened to it in his heart, but he didn't show it at all on his face.

Emperor Xiyun was excited and moved, and praised again: "Xiyun can have you and Yi'er quietly, it is Xiyun's luck!" Great luck! ”

After a pause, Emperor Xiyun asked, "Jingjing, last time you and Changyi wrote to me about grafting seedlings, it seems that it was to specialize in the problem of pests and diseases, right?" ”

Quietly nodded, "Yes." A few days ago, I went to the county with Changyi to see that the grafted cucumber seedlings grew very well, there were no pests and diseases, and there were a lot of flowers, and a lot of cucumber buds were beaten, maybe the yield would be increased, and the effect was much better than what Changyi and I expected. ”

Emperor Xiyun was even more pleased: "Then I want to go and see tomorrow, you and Changyi will take me to have a look, right?" I really wanted to see the grafted cucumber, I've never seen a pumpkin root underneath and a cucumber on top. ”

Quiet and refreshing: "Since my father-in-law wants to take a look, then Changyi and I will take my father-in-law to take a look tomorrow." ”

On the second day, Jing Jing and Xiao Changyi took Emperor Xiyun to the experimental field of the Qilin County Agricultural Institute to see the cucumbers that had been grafted before.

The cucumber vines have been wrapped around the bamboo support, and among the lush greenery, small yellow flowers are dotted like stars, and some of the yellow flowers have withered, and you can clearly see the fresh and green cucumber buds.

Underneath the vines, you can see that the roots do not belong to cucumbers, but to pumpkins.

Whether it is the cucumber vine or the cucumber leaves, there are almost no insects, unlike the few pieces around the cucumber field, the insects are particularly serious, and it forms a stark contrast.

Emperor Xiyun looked at everything in front of him, excited, and praised three good words in a row, and then turned his head and said to Jingjing: "Jingjing has made a lot of contributions, and I haven't rewarded Jingjing for such a great contribution to increasing cotton production in a nutritional bowl, and now Jingjing has set up two major achievements in rotation and grafting, I still had some consideration that Jingjing is a woman, and it is not good for Jingjing to be a big official, but now, I have nothing to take care of, Jingjing's talent is too good, and there is no agricultural official who can compare with Jingjing you." Quietly you say, whatever official you want, I'll give it all! ”

This big official, of course, is only a peasant official.

Jing Jing could understand what Emperor Xiyun meant, and said with a smile: "Father-in-law, I don't want to be a big official, I just want to help you and Chengyu solve your worries, at first I wasn't sure that I could really help you, but now I can really help, and I am quite happy." ”
