An organic fertilizer method that promotes the firing of smoke and grow up early and grows with water and fertilizer.

Abstract

The invention discloses an organic fertilizer supply method for promoting early, rapid and robust growth of tobacco seedlings by retaining water and fertilizer. On the day or the day before the tobacco seedlings are transplanted, mix the biological liquid fertilizer, fish protein organic liquid fertilizer and water according to the volume ratio of 6:0.2~1:250~350 to obtain the nutrient solution for later use. Mix the dried coconut peat and the nutrient solution according to the mass ratio of 1:5~7, soak for 2~12 hours; get the coconut peat matrix for later use. Before transplanting, bury the coconut peat matrix in the smoke pond, and the application rate of each pond is 20~40g converted into dry coconut peat. Plant the tobacco seedlings into the coconut bran matrix of Yantang, no longer water the roots after planting, and cover the surface with a layer of fine dry soil; the rest of the topdressing, watering, mulching, seedling removal, and pest control refer to the conventional transplanting of seedlings under mulch The craft is carried out. The fertilizer supply method fully utilizes the characteristics of loose texture, large pores, low water content, low bulk density, and strong water absorption and moisture retention of the coconut peat substrate, and adopts the nutrient solution fertilizer supply method, so that the coconut peat substrate can also provide sufficient water and fertilizer. Ensure enough air gaps to promote the early and rapid growth of tobacco seedlings.

Description

technical field [0001] The invention belongs to the technical field of tobacco seedling tending, and in particular relates to an organic fertilizer supply method for promoting early, rapid and robust growth of tobacco seedlings by retaining water and fertilizer. Background technique [0002] Coconut is processed to produce a large amount of coir peat, which is an active matrix with excellent physical and chemical absorption capacity and strong buffering effect. In many areas, coconut peat is either lost by incineration or is naturally degraded by a large amount of accumulation, causing great pressure on the environment. Widely used in agricultural and forestry production. The background of this technical invention is mainly reflected in three aspects: (1) In tobacco cultivation, the application of organic fertilizer is the material basis for ensuring high-quality and suitable production of tobacco leaves, but if the method of fertilizer supply is unreasonable, it will not o...

The background of this technical invention is mainly reflected in three aspects: (1) In tobacco cultivation, the application of organic fertilizer is the material basis for ensuring high-quality and suitable production of tobacco leaves, but if the method of fertilizer supply is unreasonable, it will not only cause waste of resources, but also lead to nutrient imbalance in the soil , will also cause adverse effects on the quality of tobacco leaves, and hinder the development and improvement of lean production of modern tobacco agriculture; (2) Kunming Tobacco Area is mainly distributed in mountainous areas and semi-mountainous areas, with poor water conservancy conditions and unbalanced soil essential micronutrient elements for plants , the fast-growing group tree period and the prosperous long-term intermittent drought weather are prominent, which is unfavorable to the healthy growth of tobacco plants; (3) With the rise of large-scale agricultural and environmental protection production, microbial organic fertilizers, disease prevention and insect control preparations have been widely promoted and applied , the colonization (survival) environment of these beneficial microorganisms needs a certain humidity requirement, but due to unstable soil moisture, these microbial agents often cannot play their due role
