In the autumn, as the temperature gradually decreases, the illumination time is shortened, and the condition of the vegetables is improved. However, there are still many local vegetable growers. The vegetables in the shed are overgrown, and the vegetative growth and reproductive growth are not coordinated, which affects flower bud differentiation and fruit growth. For the current environmental conditions, and want to control the length of the plant, the vegetable farmers should adjust from the following two aspects.
Adjusting top dressing
The vegetative growth of plants is too strong, and there are often more nitrogen fertilizers in the soil, especially ammonium nitrogen fertilizers. To control the length of 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 mix with a variety of pesticides, often increasing the impact on flower bud differentiation, melon growth, etc., so it is not recommended to mix.
