Use of poly-gamma-glutamate in burley tobacco field production

Abstract

The invention relates to the application of poly-Gamma-glutamate in the land production of burley tobacco, and the poly-Gamma-glutamate is poly-Gamma-glutamate wettable power which is used in a plurality of periods during the growth of burley tobacco, and the dosage of the poly-Gamma-glutamate wettable power is 200 to 400 grams per mu. Or the poly-Gamma-glutamate is a special synergistic fertilizer of poly-Gamma-glutamate tobacco which is used in a basic fertilizing period and an additional fertilizing period or used in the basic fertilizing period and the additional fertilizing period at thesame time, and the dosage of the special synergistic fertilizer of poly-Gamma-glutamate tobacco is 20 to 30 kilograms per mu. As a biodegradable fertilizer absorption accelerant, the poly-Gamma-glutamate generates good effects of improving soil structure, increasing the soil capacity of preserving moisture and fertility and slowly releasing chemical fertilizer; the invention not only can save fertilizer and reduce soil damage and environmental pollution which are caused by overusing fertilizer, but also can effectively improve the production quantity and quality of the burley tobacco.

Description

technical field [0001] The invention relates to the application of poly-γ-glutamic acid in field production of burley tobacco, belonging to the field of microbial fertilizer application. Background technique [0002] Burley tobacco is a light-colored air-dried tobacco. Burley tobacco is a mutation of the Maryland tobacco variety. After it was discovered in the Maryland tobacco planting field in 1864, it was specially planted and proved to have special use value, and gradually developed into a new tobacco type. [0003] Soil is the material basis for the survival of crops. It is not only the substrate for crop growth, but more importantly, it is the intermediary for crop nutrient absorption. The physical and chemical properties of the soil itself are directly related to the growth of crops. Therefore, in tobacco planting, soil quality is one of the important factors affecting the formation of tobacco leaf quality and the fertilizer utilization rate of tobacco plants. Among t...

Problems solved by technology

Because tobacco requires a lot of fertilizers, it needs to add a lot of nitrogen, phosphorus, and potassium to the soil. Therefore, these three elements are called the three elements of fertilizers. However, excessive use of chemical fertilizers has also brought many negative effects.

Due to the low absorption and utilization rate of chemical fertilizers by crops and the limited fertilizer retention capacity of the soil itself, it not only limits the exertion of soil fertility, but also easily causes the loss of soil fertility

Years of extensive use of chemical fertilizers has resulted in phosphating of surface water sources and chemical pollution of groundwater, soil element imbalance, and soil compaction, which further destroys soil properties, reduces soil water and fertilizer retention capacity and aeration capacity, which in turn affects tobacco root systems Normal growth and development will make the tobacco nutritionally deficient, which will directly cause the decline of crop yield and quality
