Problems solved by technology

Among them, passive cold avoidance measures include deep loosening and root damage to promote early maturity, standing stalks to dry to increase grain weight, blowing old leaves to ventilate and increase temperature to promote early maturity, removing tassels to maintain points to promote early maturity, removing bract leaves to increase temperature and promote early maturity, etc. However, these measures Measures can promote early maturity to a certain extent, but cannot make corn mature normally, and also lead to reduced production; mulching, seedling raising, transplanting and warming measures can effectively protect corn from the impact of low temperature and chilling damage, but it is labor-in

Abstract

The invention relates to a low temperature-resistant yield-increasing regulator used for the corn, and a preparation method thereof. The regulator contains the components with the following concentration: 100g/L of poly-aspartate, 20.05 to 30.05g/L of plant growth regulator, 65 to 67g/L of promoting agent and speader, and the solvent is water. The low temperature-resistant yield-increasing regulator used for the corn can lead the corn to increase in yield by more than 20 percent and can improve the cold resistance and the lodging tolerance of the corn simultaneously.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a corn anti-low temperature yield increase regulator. Background technique [0002] Corn is one of the three major staple food crops in my country. Northeast China (including Heilongjiang Province, Jilin Province, and Liaoning Province) is the largest dominant corn planting area in my country, which has a huge impact on the domestic grain market. However, the Northeast region is located between 38° and 53° north latitude, with high latitude and large span. The annual average temperature is 0.5-6°C, low temperature and low accumulated temperature. Chilling damage is the main factor that leads to low and unstable corn yields, and severe chilling damage can reduce production by more than 10 billion kilograms per year. [0003] Since the founding of the People's Republic of China, there have been 5 more serious cold damage years, namely 1954, 1957, 1969, 1972, and 1976. The frequency of ...
