Rice mechanical transplanting and seedling seed dark germination method

Abstract

The invention provides a rice mechanical transplanting and seedling seed dark germination method. Rectangular seedling plates are used for sowing and seedling, wherein a side wall with a certain height is arranged at the periphery of each rectangular seeding plate, a downward convex rib in frame form is arranged at the external bottom of each rectangular seedling plate, the seedling plates are overlapped after sowing, and the seedling plate at the top is further covered, so that each sowing and seedling plate can germinate under dark environment. The rice mechanical transplanting and seedling seed dark germination method provided by the invention has the benefit effects that the moisture is easy to control, the temperature of the seedling environment is easy to realize and the energy for regulating the temperature is saved; the rice seedling plates are fast in germination, the bud length can achieve 5-10mm after 2-3 days, the germination of the rice seed is neat, and the embryo is sturdy, after the germination, the rice seedling plates are moved to the environment with light, the rice seedling can grow fast. According to the rice dark germination method, the germination of the rice seedling can be accelerated, and the neatness of the germination of the seed is improved, the operation is simple, the problems of the slow germination in the rice mechanical transplanting and seedling seed and the untidiness are solved.

Description

technical field [0001] The invention relates to rice planting technology, in particular to the field of raising rice seedlings. Background technique [0002] Rice seedling emergence is an important link in rice production. The rice seedling emergence process requires suitable temperature, moisture and oxygen. The emergence of rice seedlings is easily affected by the soil environment and weather. Problems such as rotten seeds, rotten seedlings, irregular seedling emergence, poor seedling quality, and frequent seedling diseases often occur. Rice machine transplanting mainly adopts blanket seedling machine transplanting technology. Blanket seedling raising usually uses a standard seedling tray, put seedling soil or seedling substrate in the seedling tray, sow the seeds on the soil, and then cover the seeds with soil. After the seeds grow Form blanket seedlings. Therefore, seed emergence is extremely important for the formation of blanket seedlings, especially for hybrid rice ...
