AI Technical Summary

Technical Problem

After the long-term use of inorganic nitrogen fertilizer, the prior art leads to negative effects such as soil slabs, inhibits plant growth, and other means such as gene knockout are costly and complex in operation, which is not suitable for large-scale promotion.

Method used

It provides a negative regulator of protein TaARE1. Through the use of the composition curcumin and erythrocyta powder, the expression of protein TaARE1 is inhibited, the plant's tolerance to a low-nitrogen environment is improved, and the soil nitrogen supply is enhanced through auxiliary materials such as bran, soybean meal, etc.

Benefits of technology

By inhibiting the expression of the protein TaARE1, the growth ability of plants in a low-nitrogen environment is improved, the amount of nitrogen fertilizer is reduced, the soil is slab-free, the root growth is promoted and the growth rate of plants is improved.

Abstract

The invention belongs to the technical field of plant growth regulation and control, and particularly relates to a protein TaARE1 negative regulation and control agent and application of the protein TaARE1 negative regulation and control agent in regulation and control of plant low-nitrogen resistance. In the invention, the protein TaARE1 negative regulating agent is a product for inhibiting the expression of the protein TaARE1 and comprises curcumin and haematococcus pluvialis powder, and the mass ratio of the curcumin to the haematococcus pluvialis powder is 1: (10-20). The protein TaARE1 negative regulating agent is used for preventing a signal channel in the protein TaARE1 expression process and inhibiting the expression of the protein TaARE1, so that the tolerance of plants to a low-nitrogen environment is improved, the low-nitrogen resistance of the plants is enhanced, the application amount of nitrogen fertilizer can be reduced in the growth process of the plants in the low-nitrogen environment, and the yield of the plants is increased. The problem of soil hardening caused by nitrogen fertilizer use can be avoided.
