Problems solved by technology

2. Prosperous growth leads to a small number of female flowers and poor development
3. Prosperous growth leads to large leaves, which affects the ventilation and light transmission of the field, and there are many diseases
4. Affect the production in the middle and late stages
Common thriving control agents on the market are chlormequat, paclobutrazol, etc. These agents are growth retardants, which are gibberellin antagonists, which can reduce the activity of gibberellin in plants, thereby inhibiting cell elongation, bud growth, and growth. The growth of stems, however, long-term use of chlormequat and paclobutrazol are prone to phytotoxicity, therefore, new crop control agents are needed

Embodiment 1

[0035] 1. Material preparation

[0036] Test object: Wheat (Yunong 495)

[0037] After the wheat seeds were sterilized by 5% sodium hypochlorite for 10 minutes, they were germinated at 25°C for 1 to 2 days, sown in flower pots, and used for the test when they grew to two leaves and one heart.

[0038] 2. Application method

[0039] Wheat seedlings with similar growth were selected and divided into 5 treatments (3 chemical treatments, 1 positive control treatment, and 1 blank control), with 4 pots of wheat plants in each treatment, and 25 wheat plants in each pot. Measure the plant height and stem length of each wheat, and then spray different concentrations of coronatin (COR) in the chemical treatment, the positive control treatment sprays paclobutrazol with a conventional concentration of 750ppm, and the blank control sprays the same amount of water, and the same amount is sprayed to The leaves are all moist. 10 days after the application of the pesticide, a photo survey w...

Abstract

The invention relates to application of coronatine in crop vigorous growth control, and belongs to the technical field of crop cultivation. The technical problem to be solved by the invention is to provide a new application of the coronatine, namely, the application of the coronatine in crop vigorous growth control, and the application concentration of the coronatine is greater than 1ppm. The invention provides the new application of the coronatine as a crop vigorous growth control agent, the coronatine can be diluted and then sprayed on crop leaves, and the purpose of controlling vigorous growth of crops is achieved. The agent is low in use concentration and low in cost, the coronatine belongs to a natural product and is good in environmental compatibility, and the problem of agent residues does not exist.

Description

technical field [0001] The invention relates to the application of coronatin in controlling the prosperity of crops, and belongs to the technical field of crop cultivation. Background technique [0002] In actual production, crops will grow vigorously, especially crops such as wheat, rice, and peanuts. Prosperous growth of crops may cause the following adverse consequences: 1. Lead to long internodes of crop plants. The first manifestation of vigorous plant growth is that the internodes of the plant become longer, resulting in a decrease in the number of leaves and affecting the accumulation of photosynthetic products. This situation is prominent on legume vegetables. On melon vegetables, the vines need to be continuously shed during the growth process. If the plant grows too vigorously and the internodes are too long, the number of leaves will be less after the vines fall, which will seriously affect the photosynthetic product. accumulation. 2. Prosperous growth leads to...
