The new vegetable fields have the disadvantages of shallow soil layer, poor permeability, poor cultivability, low soil organic matter content, low soil quality, lack of nutrients, and inadequate irrigation and drainage. Therefore, it is necessary to speed up fertilization to ensure soil nutrient balance and accelerate soil maturation. Create good soil conditions for high yields of vegetables. The method of fertilizing fertilizer is as follows:
Deep plowing and reforming of the grain fields is generally poor, and the tillage layer is only about 15 cm. It is changed to vegetable soil. Due to the increase in the number of planting pupae and the consumption of nutrients, the plowing layer should be deepened gradually to improve its physical properties. Deep plowing time can be arranged in the summer and autumn when the vegetables are out of the garden, each deep-dip twice, so that the cultivation layer of 25-40 cm.
To increase organic fertilizers to improve soil structure, there must be materials that can stabilize the structure, such as modifiers, urban organic waste, and organic fertilizers. Application of organic fertilizer can not only meet the needs of vegetables for nitrogen, phosphorus, potassium, but also promote the formation of soil aggregate structure, improve water retention and fertility and increase the buffer capacity of the soil, it is the material guarantee of fertilizing new vegetable fields.
Planting legume green fertilization legume green manure fixed nitrogen in the atmosphere, after picking the edible part, the returning of straw, especially peas, beans and other tender stems and leaves, can increase soil organic matter and nitrogen content.
Rational crop rotation of vegetables will lead to soil acidification, salinization and disease spread. In the grain reform area, special emphasis should be placed on rational rotation, making use of differences in the absorption of different varieties of vegetables, slowing down the excessive consumption of certain nutrients, and avoiding or alleviating the above-mentioned problems, so as to give full play to the potential of new vegetable fields. For example, we must arrange some mustard and peas in the rotation to absorb phosphorus and potassium that cannot be used by ordinary vegetables in the soil to improve the state of phosphorus and potassium nutrition for the next pod of vegetables. There are a variety of rotations, but one-quarter legumes should be arranged in the rotation. In addition, according to the specific conditions of each piece of land, it is necessary to take corresponding measures for the targeted treatment of “sicknessâ€. For example, for the low-lying land that often encounters internal waterlogging, the problem of water must be solved; for acidic soil, calcareous fertilizer must be applied.
The cultivation of new vegetable plots is a long-term task. It cannot be achieved in the short term. Various measures must be taken to ensure that the results are quite obvious. Localities can conduct fertilization according to local conditions.
