In the process of planting oilseed rape, the choice of bottom fertilizer is very important for the growth of oilseed rape. Bottom fertilizer not only provides the nutrients needed for the growth of rapeseed, but also improves the physical and chemical properties of the soil and improves the fertility of the soil.
So, which fertilizers should be chosen as base fertilizer when growing rape?How much base fertilizer do you need per mu?These two issues will be analyzed and analyzed next. First of all, let's take a look at which fertilizers should be chosen as base fertilizers when planting rapeseed. When choosing a base fertilizer, we need to consider the growth needs of oilseed rape as well as the nutrient status of the soil. Generally speaking, rape needs a lot of nutrients such as nitrogen, phosphorus, potassium and trace elements, so the choice of base fertilizer should be based on fertilizers rich in these elements. Common rape bottom fertilizers include organic fertilizers, chemical fertilizers, etc.
Among them, organic fertilizers include manure, compost, green manure, etc., which are rich in organic matter and various nutrients, which can improve soil structure and improve the soil's water and fertilizer retention capacity. The chemical fertilizer is a fertilizer containing a variety of nutrients prepared according to the nutritional needs of rapeseed, which has the advantages of high nutrient content and fast fertilizer efficiency. When choosing a base fertilizer, it can be matched according to the nutrient status of the soil and the growth needs of oilseed rape. If the soil is low in organic matter, a mix of organic and chemical fertilizers can be used to provide a comprehensive nutrient supply. At the same time, some trace elements, such as boron, zinc, etc., can also be appropriately added according to the growth needs of rapeseed to promote the growth and development of rapeseed.
Next, let's take a look at how much base fertilizer is needed per mu. The amount of base fertilizer should be considered according to the nutrient status of the soil, the growth needs of rapeseed and the planting density. In general, 1000-2000 kg of organic fertilizer or 20-30 kg of chemical fertilizer need to be applied per mu. At the same time, it is also necessary to add some trace elements appropriately according to the growth needs of rapeseed.
When applying base fertilizer, it is necessary to pay attention to the depth of fertilization and the method of fertilization. In general, the base fertilizer should be applied in the soil layer where the rape root system is distributed to promote the uptake of the rape root system. At the same time, it is also necessary to choose appropriate fertilization methods according to factors such as soil humidity and texture, such as strip application, hole application, etc., to ensure the effective use of bottom fertilizer and improve the growth effect of rapeseed. In addition to the application of base fertilizer, other aspects of management need to be paid attention to. For example, land should be prepared and tilled before planting to improve the soil's aeration and water retention.
Field management and pest control should be carried out in time after planting to ensure the normal growth and development of rapeseed. At the same time, it is also necessary to carry out reasonable topdressing and irrigation according to the growth status and climatic conditions of rapeseed to meet the growth needs of rapeseed and improve the yield and quality of rapeseed.
In short, fertilizers rich in nutrients such as nitrogen, phosphorus, and potassium should be selected as the base fertilizer when planting rapeseed, and should be matched and used according to the nutrient status of the soil and the growth needs of rapeseed. An appropriate amount of base fertilizer needs to be applied per mu to ensure the normal growth and development of rapeseed. At the same time, it is also necessary to pay attention to other aspects of management, such as land consolidation, field management, pest control, etc., to improve the yield and quality of oilseed rape.
