Automatic seed covering seedling raising substrate plate for rice and preparation method and application

Abstract

The invention provides an automatic seed covering seedling raising substrate plate for rice and a preparation method and application thereof, and belongs to the technical field of rice seedling raising. The automatic seed covering seedling raising substrate plate for the rice is based on the structure of a honeycomb, expanded rice husks, corn stalk, vermiculite, decomposed manure and turfy soil serve as the components, mold shaping and high temperature drying are conducted, and an initial type is obtained; each hole serves as an independent unit, and water expansion materials are used as barriers between the holes, the bottom and the periphery of a whole seedling tray are pasted and fixed with degradable paper, and according to the specification of the seedling tray applied by a rice transplanter, a rice dry raising machine is obtained for inserting an automatic seed covering seedling raising substrate plate. The automatic seed covering seedling raising substrate plate is applied for raising seedlings, not only is the seedling raising soil is replaced, but also a plastic seedling raising tray is replaced, the automatic seed covering seedling raising substrate plate can be directlyplaced for use, the process that covering is conducted again after sowing is omitted, the efficiency of rice seedling raising is improved, a substrate body suitable for cold region seedling root system growth is created, the stress resistance in the seedling growing process is enhanced, and strong seedlings are cultivated.

Description

technical field [0001] The invention belongs to the technical field of rice seedling raising, and in particular relates to a rice automatic covering seed seedling raising matrix tray, a preparation method and application thereof. Background technique [0002] Rice is one of the main crops in my country's agricultural production. Since its development, planting technology, unit output, economic benefits and many other aspects have been significantly improved, which has played an important role in ensuring my country's food security. With the development of the times, the requirements for the yield and quality of rice production are getting higher and higher. In particular, the seedling raising technology in the dry-breeding and sparse planting of rice is particularly important. As the saying goes, "the seedlings are good for half a year's grain." Cultivating high-quality seedlings is crucial to improving rice yield and quality. [0003] At present, in order to raise good se...

Problems solved by technology

[0004] With the development of the times, people also use different materials to make a lot of artificial seedling substrates to cultivate seedlings, but there are still many deficiencies in practice, such as the low rate of seedlings, and the seedlings are prone to produce aerial and aquatic roots. In Honda, the seedlings are slow, and the greening period is delayed, which affects the yield, quality and maturity period; although there are substrates to replace the seedling soil on the market, the product cannot guarantee the integrity of the root system during mechanical transplanting and replace the original plastic seedling tray. cumbersome, expensive, etc.
