How to fertilize new vegetable fields effectively
2021-06-12 12:03:38
Most new vegetable fields have shallow soil layer, poor permeability, poor cultivation, low soil organic matter content, low soil quality, lack of nutrients, and lack of support for irrigation and drainage. Therefore, fertilization should be accelerated to ensure soil nutrient balance and accelerate soil ripening. High yield creates good soil conditions. The method of fertilizing fertilizer is as follows:
1. Deep ploughing and improving the soil quality of the soil grain field is generally poor. If it is changed to vegetable soil, the cultivating layer should be gradually deepened 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 tillage layer of 25 to 40 cm.
2. The application of organic fertilizers to improve soil structure requires the existence of substances that can stabilize the structure. Applying organic fertilizers can not only supply the vegetables' needs for nitrogen, phosphorus, and potassium, but also promote the formation of soil aggregates and improve the ability to retain water and fertility. And increase the buffer capacity of the soil.
3. Plant legume green fertilizer legume green manure fixed nitrogen in the atmosphere, after picking up the edible part, returning the straw to the field, especially the tender stems and leaves of peas, broad bean and so on, can increase soil organic matter and nitrogen content .
4. Rational rotation in the grain reform area, should pay special attention to reasonable rotation, use of different varieties of vegetable fat absorption differences, slow down the excessive consumption of certain nutrients, to avoid or reduce the emergence of the above problems, so as to give full play to the production of new vegetable fields potential. For example, we must arrange some mustard greens and peas in the rotation to absorb phosphorus and potassium that cannot be used by ordinary vegetables, and to improve the state of phosphorus and potassium nutrition for the lower-lying vegetables. There are a variety of rotations, but one-quarter legumes should be arranged in the rotation.
