Seed selection and seed-soaking germination acceleration method of paddy rice cultivation

Abstract

The invention disclose a seed selection and seed-soaking germination acceleration method of paddy rice cultivation. The cultivation method is realized through the following steps: (1) seed sun-drying is carried out, wherein the seeds are sun-dried for 3-4h in a sunny day, such that seed germination rate and germination energy are improved; (2) seed selection is carried out, wherein the seeds are selected with clear water; floating grains are removed; imperfect seeds are fully utilized; and germination acceleration and sowing are respectively carried out; (3) seed soaking and disinfection are carried out. The seeds are cleaned with clear water, and are pre-soaked for 12h in clear water, such that germ spores attached on the seeds emerge; the seeds are then soaked for 12h with a trichloroisocyanuric acid agent liquid diluted by 300 times; and (4) germination acceleration is carried out. In a conventional germination acceleration process, soaked and disinfected seeds are fetched and drained; the seeds are preheated for 3-5min by washing the seeds with water with a temperature of 35-40 DEG C; the seeds are placed in a cloth bag or a basket; the periphery of the bag or basket is sealed with an agricultural film and disease-free straw, such that thermal insulation is realized.

Description

technical field [0001] The invention relates to a planting method, in particular to a method for seed selection and seed soaking and accelerating germination of rice planting, and belongs to the field of planting methods. Background technique [0002] Mastering the soaking time and method of rice is the key to improving the germination rate of rice. With the change of farming system and the diversification of rice cultivation methods, if rice soaking and accelerating germination are still stick to the old rules, it will often result in too long soaking time of rice seeds, release of seed nutrients, and peculiar smell leading to uneven germination and low germination rate. Low, even lead to the phenomenon of high temperature burning buds in the process of germination. Contents of the invention [0003] Based on the existing rice planting method, the present invention adopts innovative scientific principles to propose a method for rice planting seed selection and seed soa...
