First, the principle of fertilization.
The principle of fertilization is based on the soil fertility, through the role of soil microbes to supply crop nutrients, requires organic fertilizers, supplemented with biological fertilizers, and appropriate cultivation of green manure crops to fertilize the soil.
Second, the type of fertilizer
1. Farmyard manure, such as compost, manure, biogas fertilizer, green manure, crop straw, mud fertilizer, cake fertilizer, etc.
2. Biological bacterial fertilizer, including humic acid fertilizer, rhizobial fertilizer, phosphorus bacterial fertilizer, and compound microbial fertilizer.
3, green manure crops, such as grass carp, Chinese milk vetch, Tian Jing, ramie, alfalfa and so on.
4, organic compound fertilizer, such as Yililai active (biological) organic fertilizer, green solar liquid fertilizer, Yi'an Shenli and so on.
5. Wastes from other organic production, such as bone meal, amino acid residues, livestock processing waste, and sugar factory waste.
Third, pay attention to the problem
1. Manure and manure should be fully fermented and decomposed, preferably by biological bacteria, and rinsed with water after top dressing. In addition, human feces and urine contain high levels of nitrogen, and should not be applied too much on crops such as potatoes, melons and beets.
2. Straw-based fertilizers are prone to cause soil hypoxia in the process of mineralization and produce plant toxins, which are required to be turned into soil before crops are planted or transplanted.
3, organic compound fertilizer is generally a long-acting fertilizer, when applied, it is best to apply farmyard manure to improve fertilizer efficiency.
Fourth, the application method
1. Base fertilizer: Combine 3000-5000 kg of composted or composted per mu, and use organic compound fertilizer as seed fertilizer, such as Yililai active (bio) organic fertilizer 100 kg, “Fengyi†brand Organic compound fertilizer 60-70 kg. The method is to apply the ditch strip or the hole under the seed or the seedling before transplanting or sowing. The fertilization depth is preferably 5-10 cm, pay attention to the middle interval soil.
2, top dressing: topdressing soil fertilization and foliar fertilization. Soil topdressing is mainly carried out in combination with watering and soil cultivation in the vigorous growth period of vegetables, mainly using human excrement and bio-Puli fertilizer. Foliar fertilization can select bio-organic foliar fertilizer in the seedling stage and growing season, such as the 500-fold liquid solution and the 500-fold liquid solution of Yi'an Shenli, spray once every 7-10 days, and spray 2-3 times.
Green manure is generally rolled over during flowering, with a depth of 10-20 cm, and a pressure of 1000-1500 kg per acre. The turning time can be determined according to the decomposition speed of green manure.
In addition, fertilization should be based on the characteristics of the fertilizer and different soil properties, different vegetable types and different growth and development periods, and scientific application, in order to effectively fertilize the soil and improve crop yield and quality.
