Temperature-control seedling raising method of rice in greenhouse

Abstract

The invention provides a temperature-control seedling raising method of rice in a greenhouse, and relates to the technical field of planting of rice. The method comprises the following steps of building the greenhouse; performing sowing in good time; treating seeds: firstly, selecting seeds by a water test method before sowing, soaking the seeds with mixed liquid of potassium pyrophosphate and lithium diisopropylamide, of which the mass concentration is 1-5% at 15-20 DEG C, for 2-3 days, wherein the proportion of the potassium pyrophosphate to the ithium diisopropylamide being (3-4) to 1, finding that rice husk is translucent, the rice bodies are white and clear, and the germs are expanded through observation, and performing disinfection treatment; then performing coating with a coating material, performing drying until sticking hands disappears, and then performing sowing; performing a sowing method; and performing field management. The germination accelerating effect is good, the germination percentage is high, the survival rate is high, the operation is simple and convenient and the cost is low.

Description

Technical field: [0001] The invention relates to the technical field of rice planting, in particular to a method for temperature-controlling and raising seedlings in a rice greenhouse. Background technique: [0002] Oily rice greenhouse seedling raising technology is an advanced practical technology to realize early breeding of strong seedlings, early transplanting of seedlings, overcoming low temperature and chilling damage, and gaining high yield. Compared with conventional seedling raising, rice seedling raising in greenhouses has low investment cost, simple operation, convenient management and wide application range. It is an ideal seedling raising method in the north at present. The seedling raising method of rice in the prior art is relatively simple and has the following shortcomings. 1. The seed of rice is hard, and the effect of accelerating germination by soaking in ordinary warm water is poor. The germination rate is low; 2. In ordinary seedling raising, more fertilize...

Problems solved by technology

[0002] Greenhouse seedling raising technology of oily rice is an advanced and practical technology to achieve early seedling cultivation, early transplanting, overcoming low temperature and chilling damage, and obtaining high yield. Compared with conventional seedling raising, rice greenhouse seedling raising has low investment cost, simple operation, convenient management and wide application range. Features such as, be the relatively ideal seedling raising mode in the north at present, the seedling raising method of paddy rice in the prior art is relatively simple, has following shortcoming, 1, the seed of paddy rice is harder, the effect of the mode vernalization of only soaking vernalization by common warm water is relatively poor, Resulting in a low germination rate; 2. More fertilizers need to be applied during ordinary seedling cultivation, and the cost is high
