rice seedling tray

Abstract

The invention discloses a rice seedling growing tray which is prepared according to the method comprising the following steps: (1) dosing plant straws, chicken manure, bean pulp, shrimp shells, diatomite, zeolite powder, weathering coral, 25-35 parts of black false hellebore, rheum officinale, fructus kochiae, polygonum cuspidatum, carpesium abrotanoides, Bupleurum scorzonerifolium, Hedyotis biflora, castor bean, pokeberry root, rhizome of dryopteris, rhizoma galangae, loquat root, aspongopus and scirpus maritimus; (2) fermenting the plant straws, chicken manure, bean pulp and shrimp shells; (3) sintering the weathering coral; (4) dissolving the sintered substance in water, mixing with zeolite powder, and irradiating by using far infrared rays; (5) decocting the traditional Chinese medicines to obtain the filtrate; (6) soaking the diatomite in the decocted filtrate; (7) uniformly mixing the materials obtained in the previous steps; and (8) performing compression molding. According to the seedling growing tray, the rice yield can be improved, the plant diseases and insect pests are controlled, and the ratio of lysine in proteins can be improved, so that the quality and taste of the rice are improved.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a rice seedling raising tray containing a nutrient matrix. Background technique [0002] The fruit of rice is actually paddy, and paddy (grain) is called rice, fragrant rice, rice after shelling. Nearly half of the population in the world feeds on rice. my country is a big country in rice planting and rice production. Since most rice seedlings are raised using dry-breeding and sparse planting techniques, a large amount of topsoil of 15-20 cm of high-quality upland cultivated land needs to be collected every year as seedling bed soil, which causes a large amount of cultivated land topsoil loss. CN101828490A discloses an environmental protection tray for rice seedling raising, which is made of raw materials such as crushed corn stalks and industrial waste slag through processes such as raising and stirring. It can replace traditional seedling soil and be used as a seedling raising subs...

Problems solved by technology

CN101828490A discloses an environmental protection tray for rice seedling raising, which is made of raw materials such as crushed corn stalks and industrial waste slag through processes such as raising and stirring. It can replace traditional seedling soil and be used as a seedling raising substrate. The effect of killing soil germs, the quality of seedlings is also slightly improved compared with ordinary soil, but the degree of improvement is not significant

In the prior art, there are many reports similar to the above-mentioned disclosed seedling raising substrates, but these substrates can only guarantee the rice yield and disease resistance of rice, and make little contribution to the quality of rice and the nutritional value and mouthfeel of rice produced

Studies have shown that the yield of rice is negatively correlated with the protein content, that is to say, the contribution of the seedling substrate to rice planting is often lost, and it is difficult to balance the yield and nutrition
