Water-saving high-yield cultivation technology for precisely attaching seeds to rice membrane

Abstract

The invention discloses a water-saving high-yield cultivation technology for precisely attaching seeds to a rice membrane. The technology includes the following steps that first, a field is levelled and fine raked; second, a high-yield late-maturing lodging-resistant variety is selected; third, the seeds are precisely attached to the membrane through a machine; fourth, the membrane is made to cover the field for cultivation; fifth, formulated fertilization is performed; sixth, water management is performed. The technology has the following yield increasing advantages that first, the seeds are precisely attached under the rice membrane, and seedling growing, transplanting and restoring are not needed; second, the seeds are covered with the mulch, the moisture in the field is low, and pathogenic bacteria cannot be bred and spread easily; third, growth of weeds can be effectively restrained due to the membrane covering, and the technology is favorable for developing green rice production; fourth, the temperature under the membrane is high, and conversion and absorption of organic matter are promoted; fifth, the seeds are attached under the membrane, rice grows fast, and the root systems are strong; sixth, physiological water needs of rice are optimized, and water saving and yield increasing are achieved. Due to the technology, seedlings can be short, strong and good in cold tolerance and bear large ears and more grains, the cost saving and yield increasing effects are remarkable, rice cultivation is made the same as corn and soybean cultivation, labor is saved, and the production is more convenient and efficient to carry out.

Description

technical field [0001] The invention relates to agricultural planting technology, in particular to a water-saving and high-yield cultivation method for accurately attaching seeds to rice film, that is, precisely positioning on the film, attaching precise amounts of seeds to the film, and covering the rice field with the film. Background technique [0002] In recent years, rice planting in northern my country has attracted more and more attention from farmers due to its high yield and remarkable economic benefits. Traditional rice planting requires the construction of seed soaking and accelerating germination workshops, seedling raising sheds, the purchase of seedling trays for seedling raising, and the need to take guest soil as Nutritious soil, the production process includes seedbed making, arranging, sowing, weeding, temperature and humidity management in greenhouses, seedling transportation, and labor for transplanting. It is the key link that restricts the quality and yie...

Problems solved by technology

[0003] The purpose of the present invention is to provide a precise water-saving and high-yield cultivation method for rice seedlings attached to film, so as to solve the problems of excessive labor intensity of existing rice seedling raising and transplanting techniques, diseases at the seedling stage, delayed seedling transplanting, or live broadcasting in dry fields and low-lying land prone to waterlogging. Difficult rice seedling emergence, weak seedlings, low yield, high water consumption, lack of water resources and many other problems
