A kind of simultaneous sowing cultivation technique of wheat and rice

Abstract

The invention relates to wheat rice common sowing cultivation technology which is characterized in that when autumn harvest is carried out in the middle and lower reaches of Yangtze river, a straw shredding device is arranged on a harvester, rice straw is shredded into small segments and scattered evenly for returning to field, base fertilizer is applied according to normal usage of wheat fertilizer application, for sowing, wheat and rice are respectively selected according to local production sowing quantity, mixed evenly and sowed, when the wheat is mature and harvested in summer of the next year, wheat straw is returned to the field, rice germination and growth are waited, and follow-up rice management measures can be carried out according to normal production. Rice seed lives through the winter in a dormant mode, after temperature rises again the following year, conditions for rice seed germination are mature, the wheat is about to be mature and harvested, rice sprouts and grows normally after the wheat is harvested, and therefore sowing tasks of the two crops can be finished only by sowing once in autumn each year. Accordingly, labor intensity of farmers is lowered, labor force is liberated, and manpower, material resources, financial resources and time are saved greatly.

Description

technical field [0001] The invention relates to a simultaneous sowing cultivation technique of wheat and rice. Background technique [0002] Rice and wheat are the two major food crops in my country. [0003] In our country, wheat is grown everywhere. The national winter wheat area and total production account for about 84% and 90% of the total wheat area, mainly distributed in the south of the Great Wall, and the main producing provinces are Henan, Shandong, Hebei, Jiangsu, Sichuan, Anhui, Shaanxi, Hubei, Shanxi and other provinces. [0004] The division of rice in my country is: the double-cropping rice cropping area in South China, south of Nanling; Single-cropping rice cultivation area, north of the Huaihe River in the Qinling Mountains, south of the Great Wall; early-maturing single-cropping rice cultivation area in Northeast my country, northwest of the Liaodong Peninsula and north of the Great Wall, east of Daxingan Mountains; single-cropping rice cultivation area in...

AI Technical Summary

Problems solved by technology

The cultivation of each crop requires a farming process. Farmers are more laborious, use agricultural machinery frequently, and consume more energy.

[0006] In addition, with the frequent occurrence of natural disasters (especially the drought in summer), it has seriously affected agricultural production

Especially in the case of lack of water resources during rice planting, "difficulty in irrigation" is a common and prominent problem: leading to older rice seedlings, late transplanting, short growth period, low yield, and poor rice quality, which seriously restricts the improvement of agricultural benefits
