Fertilization techniques for vegetables in greenhouse in early spring

The temperature in spring is lower, but the temperature in early spring is still low, and the light is relatively weak, which will result in weak seedling growth and thinner stems. The seedling stage is the basis of flowering and fruit setting, whether the seedling growth is strong or not, related to the late flowering and fruiting, of which fertilization is a very large part, so how to apply fertilizer to vegetable seedlings in the greenhouse in early spring? Come and have a look with the editor.

1. Adjust the ratio of base fertilizer

It is very easy for vegetables to grow in the seedling stage, which is closely related to the content of nitrogen fertilizer in the base fertilizer. at present, the manure of poultry and livestock is the most commonly used in many farmers, the nitrogen content of this fertilizer is very high, and it mainly exists in the form of uric acid. after being applied to the soil, it will be converted to ammonium nitrogen, which is the easiest to promote overgrowth. In order to control the excessive growth of vegetables in the seedling stage, adjusting the ratio of base fertilizer is the key. It is suggested that farmers should increase the fermented manure and straw in the base fertilizer, turn the soil deeply, and properly match the rotten soybean meal organic fertilizer, medium and trace element fertilizer, and so on. Make the ratio of base fertilizer more reasonable, which is the basis to ensure the healthy growth of seedlings.

2. Make good use of organic activated nutrient fertilizer

When the seedlings are planted, the roots can be irrigated with carbendazim + 1000-fold Jiamei bonus, which has an excellent effect on regulating plant growth and controlling vigorous growth. This is because the beneficial bacteria in the dividend can promote the transformation of nitrogen fertilizer, effectively reduce the content of ammonium nitrogen in the soil, increase the content of nitrate nitrogen, promote root rooting, improve root absorption function, and promote plant growth. However, nowadays, many farmers do not pay attention to the application of this aspect, which often results in uneven seedling quality.

3. Supplement of trace elements

When the seedlings slow down, spraying 1000 times liquid Jiamei platinum can help to adjust the proportion of nutrients in the plant, reduce the content of nitrogen fertilizer, and thus regulate the growth. In addition, when watering slow seedling water, applying organic fertilizer with water flushing can not only effectively regulate root nutrition absorption, promote root growth, improve root stress resistance, reduce plant overgrowth, but also effectively promote flower bud differentiation and improve flowering and fruiting quality. reduce abnormal fruit phenomenon, improve yield and quality.
