Method for promoting transplanted crops to absorb nutrients on basis of high-voltage electrostatic fields

Abstract

The invention relates to a method of promoting transplanted crops to absorb nutrients on the basis of high-voltage electrostatic fields. The method includes the following steps: 1 preparing seedling samples; 2 applying high voltage electric fields at different strengths to the samples; 3 measuring activity of seedling roots, penetration of leaf cell membranes and ionic concentration change of absorption liquid; 4 determining the optimum field intensity and treatment time which are favorable for nutrient absorption by the crops. The method of promoting transplanted crops to absorb nutrients on the basis of the high-voltage electrostatic fields can treat various different seedlings, determines the optimum field intensity and action time which can promote absorption of different nutrients for every kind of crop, and has the characteristics of being wide in application and simple to operate.

Description

technical field

[0001] The invention relates to a method for promoting nutrient absorption of transplanted crops based on a high-voltage electrostatic field. The invention belongs to the field of crop production technology, and is specially used to promote the rapid absorption of nutrients in transplanted crops and realize rapid nutrient supplementation. Background technique

[0002] Nitrogen, phosphorus and potassium are indispensable nutrients in the process of crop growth and development, and play a vital role in crop growth and development. Nitrogen fertilizer and phosphorus fertilizer are the two most used fertilizers. Although the application amount of potassium fertilizer is relatively small, the potassium resources in our country are limited, and potassium fertilizer needs to be imported. However, at present, my country's fertilizer utilization rate is low, and nutrient loss is serious. The ratio of nitrogen, phosphorus, and potassium is not in harmony with the supp...
