A kind of paddy rice automatic mulching seed seedling raising substrate tray and its preparation method and application

Abstract

The invention provides a paddy rice automatic covering seedling raising matrix tray, a preparation method and an application thereof, and belongs to the technical field of rice seedling raising. The rice automatic covering seed seedling raising matrix plate is based on the honeycomb structure, with expanded rice husk, corn stalks, vermiculite, decomposed manure and grass carbon soil as components to obtain the initial shape through mold molding and high-temperature drying, with the hole as an independent unit, each hole Water-expandable materials are used as barriers in between, and the bottom and periphery of the whole seedling tray are pasted with degradable paper to solidify the shape. According to the specifications of the seedling tray used by the rice transplanter, a paddy seedling matrix tray product that automatically covers seedlings for rice transplanting is made. Apply rice automatic mulching seedling raising substrate tray to raise seedlings, which not only replaces seedling raising soil, but also replaces plastic seedling raising trays. It can be placed and used directly, saving the process of covering again after sowing, improving the work efficiency of rice seedling raising, and creating a root system suitable for seedling raising in cold regions. The matrix body enhances the stress resistance during the growth of the seedlings and cultivates strong seedlings.

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.
