Want to control the stems and leaves, first of all, pay attention to adjust the proportion of topdressing. In general, plants with long lengths should be eliminated from ammonium nitrogen fertilizers (ammonium sulfate, etc.) or fertilizers that can be converted to ammonium nitrogen fertilizers (such as urea), and the use of nitrate nitrogen should be appropriately reduced to adjust nutrient balance in plants and alleviate The situation is long. It is recommended to have a long-term situation in the greenhouse. When topdressing, you can choose potassium dihydrogen phosphate, suspended calcium, etc., and focus on potassium, calcium, phosphorus, etc., to coordinate plant growth, cultivate strong trees, and improve resistance.
Hormone control
The growth of vegetables is prosperous, and the proper use of plant growth regulators is the most rapid and effective measure. However, excessive use will affect the growth rate of melon strips, resulting in shorter and smaller melon strips and obvious side effects.
When the vegetables are long, you can use chlorophyll 1500 times, etc., and spray the plant growth points to inhibit the growth of stems and leaves. It should be noted that the plant growth regulator is preferably used alone. In actual management, many vegetable farmers often use a variety of pesticides to spray together, which will increase the impact on flower bud differentiation and melon growth, so it is not recommended to mix.
