On the same day, Yang Heyu left Daxue Township and caught the last bus back to Heliu.
The plan he was thinking of was called intercropping. Yang Heyu, who was still in college in the early years, had read foreign materials about intercropping in macadamia forests.
At that time, he didn't pay too much attention. From the bottom of his heart, Yang Heyu is more like a research talent. He has strong concentration and is good at studying. If it weren't for this trip to Daxue Township, he would not have paid attention to the deep intolerance of poor households like Lao Sun for investing in macadamia nuts for the first few years without harvest.
Now Yang Heyu feels the seriousness of this problem, because Heliu has also begun to gradually promote the cultivation of macadamia nuts to the majority of farmers. The difference from Laosun is that it is impossible for Cuizhang Fresh Products to help farmers manage the forest land for three years before delivery. People who choose to plant nut trees have to bear all the pressure from the beginning.
Yang Heyu is very grateful that this trip to Daxue Township has allowed him to see more realistic problems, and as a front-line technician, he should exist to provide technical solutions to solve such realistic problems.
When he was in Daxue Township, Yang Heyu took Lao Sun to walk through his nut forest that was almost half burned.
Yang Heyu discovered that the forest land of Laosuntou had problems from the very beginning¡ªit was too densely planted, which was not conducive to the formation of the photosynthetic surface.
So he suggested that Lao Sun simply abandon the trees that were burned most badly and expand the original planting distance. In this way, not only the remaining trees can be kept and the possibility of gradually increasing the yield will be increased, but also other trees can be planted in the remaining space. crops to increase income.
This kind of suggestion was unheard of by Lao Sun. He first said that the superiors had never allowed such a planting, and then he obviously reaped the hope. He stared at Yang Heyu and asked him if it was really feasible?
Yang Heyu only has information in his mind, and he has no practice. According to Yang Heyu's habit, there is no conclusion without practice, and he will not give a firm reply.
But at that moment, he saw longing and hope in Lao Sun's eyes, and he couldn't bear to destroy the confidence that Lao Sun had finally rebuilt, Yang Heyu nodded and said, "Sure."
That day, he sat on the ground, reviewed the past intercropping materials from memory, and then wrote the advice to Lao Sun in his notebook:
"Try to interplant legumes, such as soybeans, red beans, and mung beans; vegetables are also available, such as green vegetables, peppers, Chinese cabbage, and radishes;"
"The above plants should not be greedy for too many varieties, and there must be enough space for nut trees; at the same time, remember that the above plants are planted in rotation, and one type of crop cannot be planted for a long time;"
"Except for leguminous crops, base fertilizer should be applied to other crops before sowing and planting. Pests and diseases should be prevented and controlled in time. High-efficiency, low-toxicity and low-residue pesticides should be used."
Yang Heyu did not explain the scientific principles behind these suggestions to Lao Sun, but he thoughtfully drew some pictures to explain these suggestions so that after he left, Lao Sun could look at those pictures and recall what he confessed.
Jin Jiaojiao has nothing to do with Yang Heyu, but it's a pity that she can't always be angry with Yang Heyu for a long time. Especially when she saw Lao Sun greeting her with a radiant face again, carrying a shovel and a hoe full of energy, Jin Jiaojiao was deeply aware of Yang Heyu's charm, and all dissatisfaction was eventually replaced by admiration.
