A drought-resistant rice seed treatment agent and its application

Abstract

The invention discloses a drought-resistant rice seed treatment agent, which is composed of 3-bromopentane and manganese chloride; it is also disclosed that it is used for seed priming: after the seeds are disinfected and washed by sodium hypochlorite, the concentration is 4-6 mg / ml 3-bromopentane and manganese chloride with a concentration of 0.25 mg / ml, the seeds and the treatment agent solution were soaked in a dark environment at a temperature of 26±1°C for 12 hours according to the ratio of 1:5, and then the seeds were taken out and rinsed with water. Rinse 3 to 5 times and then dry it; it is also disclosed that it is used for seed coating: 3-bromopentane with a concentration of 12 to 18 mg / ml and a manganese chloride solution with a concentration of 2.5 mg / ml and a coating agent Mix evenly at a ratio of 2:8, then add 4 to 5 times the volume of water to dilute to form a coating solution, and place it in the container of a special seed coating machine; coat the seeds according to the ratio of solution: seed = 55:1 Operation. The present invention proposes for the first time that 3-bromopentane is used for seed priming or coating at an appropriate concentration, which has the effect of promoting plant seed germination, rooting and stem and leaf growth.

Description

technical field [0001] The invention belongs to the field of plant growth conditioners, and in particular relates to a 3-bromopentane-based treatment agent for drought-resistant rice seeds, and it is used for initiation and coating of drought-resistant rice and upland rice seeds. Background technique [0002] The shortage of water resources has become an international problem, and the traditional flood irrigation rice production mode consumes a lot of fresh water resources, which seriously restricts the sustainable development of agriculture, and it is urgent to develop water-saving and drought-resistant cultivation methods. Water-saving and drought-resistant rice refers to a new type of cultivated rice that has both the high-yield and high-quality characteristics of rice and the water-saving and drought-resistant characteristics of upland rice. Water-saving and drought-resistant rice can be dry-planted and managed, that is, it can complete the whole process of sowing emerge...

AI Technical Summary

Problems solved by technology

[0003] However, under the dry direct seeding system, water-saving and drought-resistant rice also has a low emergence rate, making it difficult to "sow all seedlings at once".

Low seedling emergence rate, uneven seedling emergence and weak growth are the key factors affecting the seedling growth of drought-resistant rice

But there is no research and report on adopting 3-bromopentane as plant growth regulator and seed treatment agent at present
