Tray-free rice seedling raising method

Abstract

The invention discloses a tray-free rice seedling raising method which is free of seedling trays and convenient for seedling fetching and carrying and is capable of shortening the rice seedling raising period, carrying out advanced mechanical rice transplanting and realizing the conveying continuity of the mechanical rice transplanting. The method is characterized by comprising the following steps: preparation of a seedling bed, selection of rice seeds and treatment before seed sowing, seed sowing and membrane covering, dredging of three ditches, rice seedling management, transplanting at a right age, and seedling fetching. According to the method, a plant fiber rice seedling raising base cloth is cut into standard rolls by a rice transplanter and then the rolls are paved on the processed seedling bed one by one to carry out seed sowing, so that the seedling trays are eliminated, the environment is protected, the production cost is reduced, and the labor and man hour are saved; the surface of the base cloth is a net structure which has tiny holes and is good in breathability, so that the raised rice seedlings are developed in root system and good in packing, the seedling stage is effectively shortened, advanced transplanting can be carried out and benefit is brought to the reviving of the rice seedlings; during the seedling fetching, the seedlings are rolled into cylinders, so that the seedling fetching is convenient, seedling dispersion does not occur, and the conveying and stacking are convenient; the seedlings are supplied to the rice transplanter in rolls for mechanical rice transplanting, so that the conveying continuity is ensured, the phenomenon of stump leakage is avoided, the mechanical rice transplanting efficiency is improved, and the yield per mu is increased.

Description

Technical field [0001] The invention involves the field of agricultural planting. Specifically, it involves a rice seedling method, especially the rice -free seedling method of rice. Background technique [0002] "South Rice, North Wheat", rice is hot and requires a lot of water to survive. It is especially suitable for planting in the southern region of my country. It is the oldest and oldest grain crop in the Yangtze River Basin.The "Opinions of the State Council on Promoting Agricultural Mechanization and the Fast and Fast Development of the Agricultural Machinery Industry" (Guofa [2010] No. 22) requires that "focusing on the popularization of rice breeding mechanization technology in the middle and lower reaches of the Yangtze River and accelerating the entire process of rice production."In the spirit of the Central Document No. 1 in 2014, it is pointed out: Strengthening the agricultural protection system -12. Accelerate the development of modern seed industry and agricultur...
