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...

Embodiment 1

[0014] The specific steps of improving the emergence quality of rapeseed blanket seedlings of the present embodiment are as follows:

[0015] The first step is to take the straw that has been dried and free from diseases and insect pests, and weave it into a straw curtain with a thickness of about 0.5-1cm with string. The width of the grass curtain is 60-65cm, and the length is 500-600cm.

[0016] In the second step, the seedling tray is loaded with bed soil, and the soil surface is about 5mm lower than the mouth of the tray. After sowing, sprinkle 0.2-0.3cm thick fine soil to cover the seeds, and arrange them neatly in the seedbed.

[0017] The third step is to cover the straw curtain on the opening of the seedling tray without direct contact with the bed soil.

[0018] The fourth step is to water evenly with a watering can, and the water flow is in the form of fine mist until the straw curtains and bed soil are fully moistened.

[0019] Step 5: Cover the straw curtain with...
