Do not just think of “Filling and Chongâ€
Now that greenhouse vegetables have reached the late stage of growth, many vegetables have appeared in later stages of defertilization. The reporter saw in the round eggplant shed of Zhu Jianzhou, Jujia Village, Tianliu Town, that there was a phenomenon where the leaves of his family's eggplant turned yellow near the growing point. Master Zhu said that after each spraying of foliar fertilizer containing zinc and iron, the yellow leaf phenomenon will be reduced a lot. However, once the plant has taken fruit or a long time, there will be yellow leaf phenomenon, and only the foliar fertilizer can be sprayed. Solved, no radical cure. It is understood that this issue raised by Master Zhu is not an isolated phenomenon. After the vegetables begin to produce results, when they need to replenish nutrients, most growers only rely on watering every time or fertilizing the leaves to supplement their nutrition.

During the fruitful period of vegetable production, organic manure, such as dry chicken manure or soybean cake, shall be applied in the operation line or planting line, and about 600-800 pounds of pounds of fertilizer may be applied per acre. These manures will be turned into the ground in combination with the ground. This method is less waste of fertilizer, but also pay attention to 10 cm away from the base of the vegetable stem to prevent injury. As these fertilizers have a long pot life, they can effectively avoid defermentation of vegetables in the later stages. Package fertilizer. It is in the vegetable colonization line or between the strain and the plant, applying or applying fertilizing material, and then covering the soil on both sides of the planting line to tightly pack the fertilizer. This method of fertilization mostly uses organic fertilizer or compound fertilizer. Make use of fertilizers. You can use fertilizers to apply around the roots. There are many fertilizer dressing methods, and each has its own advantages and disadvantages. Farmers should choose different fertilization methods according to the fertilization period and needs, and should not only look for rushing and spraying.
