Wheat/rape-rice intercropped planting method free of sowing, transplanting and ploughing

Abstract

The invention provides a wheat / rape-rice intercropped planting method free of sowing, transplanting and ploughing. The method comprises the following steps: mechanically harvesting rice and using unhusked rice falling to the ground as rice seeds, leaving the rice seeds on the surface of a wheat or rape field without ploughing, and obtaining rice seedlings without sowing through germination and growth of the rice seeds at proper temperature and humidity in the next year, wherein the yield can be flush with that of a cultivated rice transplanting field or increased by more than 5% through density shifting and blank filling. The invention provides another wheat / rape-rice intercropped planting method free of sowing, transplanting and ploughing; the method comprises the following steps: mechanically harvesting rice and using unhusked rice falling to the ground as rice seeds, thus avoiding ploughing, sowing and rice transplanting in the next year, and putting a large quantity of ducklings into a rice field during a stooling stage, wherein a water layer in the field is stirred into muddy water by the ducks, so that weeds are difficult to germinate and grow, and rice field pests are eatenby the ducks in the growth process of the ducks; the growth of the rice is supported through decomposition of straws, excrement of the ducks and supplementation of organic fertilizers; and the ducks walk in the rice field to form irregular plant spacing, so that the growth of the rice is promoted to a certain extent. The two above-mentioned methods are also suitable for planting edible weedy rice.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a three-free planting method for wheat-oil interleaved rice. Background technique [0002] Since the 1980s, the natural farming method introduced from Masanobu, Fukuoka, Japan, combined with the actual situation of modern agricultural development in my country, has initially formed the wheat-oil-in-rice technology. The feature of this technology is to follow the philosophy of the basic concept of nature, conform to the law of natural occurrence and development, make full use of and give full play to the advantages of natural resources, avoid artificial, tedious and ineffective labor in planting, and scientifically summarize and re-understand planting. The traditional craftsmanship of the industry can give full play to high-quality and green production, improve the quality of agricultural products, achieve agricultural efficiency and increase farmers' income.

AI Technical Summary

Problems solved by technology

Statistics show that when the rice in our country is harvested mechanically, the net loss caused by harvesting is at least 3% of the total output. Based on the calculation of 500Kg per mu, at least 15Kg of rice will naturally fall into the field. This scattered rice is important in modern agriculture. Among them, there is no precedent for using this part of rice because it was buried deep in the soil and rotted.
