The latest course of fertilization techniques and methods for vegetables in greenhouse in early spring

Spring temperature is low, but early spring temperature is still low, and the light is weak, will cause seedling growth weak, thin stems, this problem is still more. And seedling stage is the basis of flowering and fruit setting, seedling growth is strong, related to the late flowering and fruit, which fertilizer is a large part, so early spring greenhouse vegetable seedlings how to fertilize it? Let's take a look at it together with Xiaobian.

1. Adjust the proportion of base fertilizer

Vegetable seedling stage is easy to overgrow, which is closely related to the nitrogen content in the base fertilizer. At present, the most common base fertilizer used by many farmers is poultry and livestock manure. The nitrogen content of this fertilizer is extremely high, and it mainly exists in the form of uric acid. After being applied to the soil, it will turn into ammonium nitrogen, which is the most easy to promote overgrowth. In order to control the excessive growth of vegetables in seedling stage, adjusting the proportion of base fertilizer is the key. It is suggested that farmers add fermented and decomposed farm manure and straw in the base fertilizer, deeply turn the soil, properly match decomposed soybean meal organic fertilizer, medium and trace element fertilizer, etc., so as to make the proportion of base fertilizer more reasonable, which is the basis for ensuring the healthy growth of seedlings.

2. Use organic activated nutrient fertilizer

When seedlings are planted, they can be irrigated with hymexiline +1000 times solution of Jiamei Hongli, which has excellent effect on regulating plant growth and controlling prosperous growth. This is because the beneficial bacteria in the bonus can promote the transformation of nitrogen fertilizer, effectively reduce the ammonium nitrogen content in the soil, increase the nitrate nitrogen content, promote the root system to tie down, improve the root absorption function, and promote the growth and health of the plant. But nowadays many farmers do not pay attention to the application of this aspect, often resulting in uneven seedling quality.

3, supplement trace elements

When the seedlings are slow, spraying 1000 times solution of Jiamei melatonin helps to adjust the nutrient ratio in the plant and reduce the nitrogen content, thus regulating the growth. In addition, organic fertilizer is applied along with water when watering the seedling, which can not only effectively regulate the nutrient absorption of the root system, promote the growth of the root system, improve the stress resistance of the root system, reduce the excessive growth of the plant, but also effectively promote the differentiation of flower buds, improve the quality of flowering and fruiting, reduce the phenomenon of abnormal fruit, and improve the yield and quality.

The above is an introduction to early spring greenhouse vegetable fertilization technology. I hope it can help you. If you want to know more about it, please pay attention to us.
