Problems solved by technology

However, at present, in order to pursue organic rice, people use less or no chemical fertilizers, and only use simple organic fertilizers, and the timing of fertilization is not well controlled, so that the nutrition obtained by rice is not comprehensive, resulting in no increase in rice yield.

Embodiment

[0022] Selected species: Rou Komachi.

[0023] 1. The effect of fertilization in different periods on the thousand-grain weight of rice

[0024] Test method: During the rice filling period, topdress fermented and decomposed organic fertilizer, and put it into a snakeskin bag at an amount of 10 kg per mu, put it into the water inlet, and let the flowing water naturally bring it into the field.

[0025] The fertilizer prepared by the present invention is applied respectively at the tillering stage, jointing and booting stage, heading flowering stage and grouting stage. The preparation method of the fertilizer is as follows: the fermented and decomposed organic fertilizer includes: 30-40 parts of corn stalks, 10-20 parts of pressed soybean oil residue , 15-25 parts of pressed rapeseed oil residue, 10-20 parts of edible mushroom residue, 5-8 parts of rice bran, 10-20 parts of manure (chicken, pig, cow manure mixed in a ratio of 1:2:3), rice bran 20-23 parts of charcoal, 10-15 par...

Abstract

The invention relates to a cultivation method, in particular to an organic cultivation method for improving the thousand grain weight of rice. The organic cultivation method comprises at a rice filling stage, utilizing organic fertilizer becoming thoroughly decomposed by fermentation to perform topdressing, placing the organic fertilizer in snakeskin bags according to the quantity of 10kg per 2000 / 3 square meters, placing the organic fertilizer at water inlets of rice fields when water is fed to the rice fields, and letting flowing water naturally bring the organic fertilizer into the fields. The organic fertilizer becoming thoroughly decomposed is applied at the rice filling stage, and the thousand grain weight is increased remarkably.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a method for increasing the thousand-grain weight of rice through organic cultivation. Background technique [0002] For a long time, due to over-emphasis on yield and insufficient attention to rice quality in rice production, chemical fertilizers and pesticides have been used unreasonably in the rice production process, resulting in some harmful chemical substances remaining in rice, long-term consumption, and endangering human health. With the continuous improvement of people's living standards in our country, residents' consumption has changed from "eat enough" to "eat well", and from "eat well" to "eat safely", people pay more and more attention to the quality and safety of edible rice , the requirements are getting higher and higher, and organic rice is therefore more and more favored by consumers, and the market prospect is very broad. The development of organic rice can save farmer...
