Mud seedling raising method of transplanted seedlings for rice machine

Abstract

The invention provides a mud seedling raising method of transplanted seedlings for a rice machine. The mud seedling raising method comprises arranging a rectangular seedling bed with side walls with a certain height in the periphery as a seedling raising carrier; placing the rectangular seedling bed in a seedling raising field which is well prepared; adding rice paddy mud into the rectangular seedling bed, wherein the rice paddy mud needs to be solidly sunk with a standard that seeds fall into the mud without sinking during sowing; laying the mud flat in the rectangular seedling bed as subsoil with the thickness of 1.5 to 2.3 cm; and sowing the rice seeds and covering substrates after the sowing, wherein the thickness of the substrates can completely cover the seeds and not more than 5 mm preferably. The mud seedling raising method of the transplanted seedlings for the rice machine has the advantages of being capable of improving the seedling rate of the seedling transplanting of the rice machine, improving the uniformity of seedling emergence, promoting the growth of seedling root systems, improving the intertwining fastness of the seedlings, improving the machine transplanting effect and being simple and practical to operate and low in cost.

Description

technical field [0001] The invention relates to rice planting technology, in particular to a mud seedling raising method for machine-transplanted rice seedlings. Background technique [0002] Rice seedlings for mechanized transplanting of rice usually use standard seedling trays. Add paddy field mud soil or dry land soil or a substrate mixed with suitable seedling growth materials in the seedling trays, and then sow the seeds to germinate and grow roots. Sheets of blanket-like seedlings, rice machine transplanting requires that the seedlings must be blanketed. The use of dryland soil in machine transplanting seedling raising requires a lot of work and will destroy the soil structure of the dryland. And use the seedling raising substrate cost that is suitable for seedling growth material to mix in proportion to be higher. The use of paddy field mud soil for seedling cultivation can be obtained locally, saving labor and cost, but because the traditional paddy field mud soil ...

AI Technical Summary

Problems solved by technology

The use of dryland soil in machine-transplanted seedling raising requires a lot of work and will damage the soil structure of the dryland

However, the cost of using a seedling substrate that is suitable for seedling growth and mixed in proportion is relatively high.

The use of paddy field mud soil for seedling cultivation can be obtained locally, saving labor and cost, but because the traditional paddy field mud soil method uses paddy field mud as the bottom soil of the machine transplanting tray, then sows, and covers the seeds with mud after sowing, due to the air permeability of paddy field mud soil Poor, so that the seedling rate is low, and if the seeds are not covered with mud, the seeds will be exposed, the upper surface will lose water quickly, and the emergence rate will also be affected. Poor blanket formation of seedlings

Due to the low seeding rate of hybrid rice machine-transplanted seedlings, this phenomenon is more serious, and the machine-transplanted effect is poor
