Method for improving germination quality of blanket seedlings of rapes

Abstract

The invention relates to a method for improving germination quality of blanket seedlings of rapes and belongs to the field of the agricultural technologies. The method comprises the steps of overlapping a rice straw curtain on a plate opening of a seedling plate, enabling the rice straw curtain to be not directly contacted with bed soil, an overlapping a layer of plastic film on the grass curtain; and watering through the grass curtain. According to the method, the water retention and humidity preservation function of the rice straw is used; the heat preservation function of the plastic film is used; reasonable temperature, humidity and ventilation conditions are provided for the seedling plate; rot sprouts and dead seedlings can be avoided; and an obvious effect of improving the germination quality of blanket seedlings is achieved.

Description

technical field [0001] The invention relates to a method for improving the emergence quality of rapeseed blanket seedlings, which belongs to the field of agricultural technology. Background technique [0002] The Chinese invention patent with the application number 201210418971.9 discloses a method for cultivating rapeseed blanket-shaped seedlings, using standard rice seedling trays to cultivate rapeseed blanket-shaped seedlings, and then using a slightly modified rice transplanter to quickly plant them, which is high-speed, efficient, and labor-saving. Book. This technology provides a new solution for the mechanized transplanting of rapeseed. The cultivation quality of blanket-like seedlings is directly related to the quality of transplanting. Whether the blanket-like seedlings are evenly distributed is closely related to the distribution of transplanted vegetable seedlings and the level of cavitation rate, which ultimately affects the formation of high-yield population st...

Problems solved by technology

If no covering measures are taken after sowing, the moisture in the bare surface bed soil will be easily taken away by the air, and strong direct light will also cause rapid transpiration of the surface moisture, and the seeds will often have difficulty in germinating due to insufficient water absorption.

At the same time, due to the different water holding capacity of the bed soil, the growth of vegetable seedlings after emergence is uneven and the uniformity is poor.

In addition, the large temperature difference between day and night during sowing, low temperature, high humidity, and high soil water content in rainy days often cause slow seed emergence, serious rotten seedlings, and low seed germination and emergence rates.
