Method for fertilizer application in arid areas in earlier stage of flue-cured tobacco field planting

Abstract

The invention provides a method for fertilizer application in arid areas in the earlier stage of flue-cured tobacco field planting. The fertilizer application method is characterized by comprising the steps that 1, 600kg-800kg of farm manures are applied to each mu of area during flue-cured tobacco soil preparation to obtain base fertilizers; 2, before flue-cured tobaccos are transplanted, 30kg-40kg of ternary composite fertilizer with N, P and K in a ratio of 12 to 12 to 24, 1kg-1.5kg of borax and 1kg-1.5kg of zinc sulfate, serving as a basic fertilizer, are applied to each mu of area; 3, after the flue-cured tobaccos are transplanted for 7-10 days, 8kg-12kg of kalium nitrate fertilizer or nitrogen and potassium fertilizer at each mu is mixed with 500kg-600kg of water and then are applied; 4, after the flue-cured tobaccos are transplanted for 15-20 days, 15kg-20kg of kalium nitrate fertilizer or nitrogen and potassium fertilizer at each mu is mixed with 500kg-600kg of water and then are applied; 5, after the flue-cured tobaccos are transplanted for 40-50 days, 15kg-20kg of potassium sulfate at each mu is mixed with 500kg-600kg of water and is applied. The fertilizer application method can be used in arid areas during flue-cured tobacco transplanting and rainwater concentrated areas in the later stage, so that demands on growth nutrition in flue-cured tobacco field planting stage can be effectively met, and the quality and the yield of flue-cured tobaccos are improved.

Description

technical field [0001] The invention relates to a fertilization method for a dry area in the early stage of field planting of flue-cured tobacco, in particular to a fertilization method for the dry area in the early stage of field planting of flue-cured tobacco in a flue-cured tobacco planting area in Yunnan Province. Background technique [0002] In the production of flue-cured tobacco, rational fertilization is the basis for producing high-quality tobacco leaves. The amount, method and type of fertilization have a significant impact on the yield and quality of tobacco leaves. In the dry areas in the early stage of flue-cured tobacco planting, especially in Yunnan Province where the flue-cured tobacco is dry during the transplanting period and the rain is concentrated in the later stage, if the conventional fertilization method is used, the growth and development of the tobacco plants will be seriously misaligned with the supply of soil moisture and nutrients. On the one han...

Problems solved by technology

In the dry areas in the early stage of flue-cured tobacco planting, especially in Yunnan Province where the flue-cured tobacco is dry during the transplanting period and the rain is concentrated in the later stage, if the conventional fertilization method is used, the growth and development of the tobacco plants will be seriously misaligned with the supply of soil moisture and nutrients. On the one hand The drought in the early stage led to low fertilizer absorption rate after transplanting of flue-cured tobacco, resulting in premature loss of flue-cured tobacco and slow growth rate; Excessive soil nutrients are brought about and released, causing problems such as excessive greenness and late maturity of tobacco leaves, and quality decline

Like this, not only cause the decline of flue-cured tobacco production and quality, also cause the waste of fertilizer
