Method for soilless simple rice seedling raising of machine-transplanted rice

Abstract

The invention belongs to the technical field of rice seedling raising and provides a method for soilless simple rice seedling raising of machine-transplanted rice and a soilless rice seedling raising plate for the machine-transplanted rice. The rice seedling raising method comprises the first step of laying a frame, the second step of laying a mulch, the third step of spreading rice husks and laying a non-woven fabric, the fourth step of sowing seeds, the fifth step of spraying water, the sixth step of setting up an arched shed, covering the arched shed with a shed film, and waiting for the growth of rice seedlings. Compared with traditional rice seedling raising through nutrient soil (matrix), the method completely abandons the nutrient soil (matrix) adopted in a traditional rice seedling raising method, and the length of a rice seedling block can be 3-6 m while the weight of the rice seedling block is only 1 / 6 to 1 / 4 of a conventional nutrient soil (matrix) rice seedling block. The rice seedling raising cost of the method is reduced by 39.6% compared with traditional hard disk rice seedling raising and is reduced by 75.5% compared with a long blanket type rice seedling raising method; the labor input for the rice seedling raising is saved by 37.7% compared with a traditional hard disk rice seedling raising method and does not differ much compared with a long blanket type rice seedling raising method; and the machine-transplanted efficiency is improved by 13.9% compared with the traditional hard disk rice seedling raising method and does not differ much compared with the long blanket type rice seedling raising method.

Description

technical field [0001] The invention belongs to the technical field of seedling raising methods, and relates to a simple soilless seedling raising method for machine-transplanted rice and a soilless seedling-raising board for machine-transplanted rice. Background technique [0002] At present, the well-known domestic rice mechanized transplanting and seedling raising technologies are mainly blanket seedling raising and pot seedling raising technology that has emerged in recent years, and the related technologies are mature. However, the above rice seedling raising methods all use soil or a new type of substrate as the seedling raising medium to rely on plastic trays for seedling raising. On the one hand, the seedling tray with seedling soil weighs about 5kg. and other agricultural operations require a lot of manpower input, and it is easy to cause damage to the seedlings and seedlings; on the other hand, the size of the seedling trays is 28×58cm 2 , in the process of machin...

Problems solved by technology

However, in actual production, due to the influence of the seedling packing force, the rate of seedling transplanting in loose trays is high, which cannot meet the agricultural operations such as seedling lifting, seedling transportation, and machine transplanting, which seriously restricts the development of seedling transplanting.

At the same time, due to the low sowing amount of hybrid rice, the root packing force is low, so that the root system of the seedlings cannot be coiled into lumps, which has become a major problem that limits the popularization and application of hybrid rice machine transplanting.
