Vegetable crops have the characteristics of high yield, high economic benefit, short growth cycle and fast rotation, and the absorption of nutrients in the soil is very large. Therefore, when planting vegetables, we must pay attention to the cultivation of vegetable fields. First, reasonable application of organic fertilizer. Organic fertilizers mainly include human excrement, manure, compost and green manure. Reasonable re-application of organic fertilizer can improve soil structure and improve soil fertility on the one hand; on the other hand, organic fertilizer will produce a large amount of carbon dioxide during decomposition, which can promote photosynthesis of plants, increase nutrients and increase yield. Second, deep cultivation. Deep cultivation of vegetable fields can make the soil have a deep and well-structured tillage layer to accelerate the decomposition of organic fertilizer, which is beneficial to the proper extension of vegetable roots and nutrient absorption, and can improve the soil's ability to prevent flooding and drought. Third, rational rotation is also an important part of vegetable cultivation. It refers to the rotation of plants on the same vegetable field in accordance with the predetermined crop type and order within a certain period of time. Pay attention to the following points when rotating: 1. Nutrients need different vegetables to rotate each other. For example, leafy vegetables with more nitrogen can be rotated with fruits and vegetables with more phosphorus; 2. Deep-rooted vegetables (such as melons) and shallow Rotation of root vegetables (such as green leafy vegetables); 3. Vegetables with different types of pests and diseases are rotated by each other. For example, the bacterial wilt is mainly harmful to the vegetable of the Solanaceae, and does not harm the cruciferous vegetables, so they can rotate each other. Linyi Fertilizer Network Copyright
