Method for transplanting rape in ill-drained paddy field

Abstract

The invention relates to a method for transplanting rape in imperfectly drained rice fields, which belongs to the technical field of agricultural planting and is characterized in that a drainage ditch (1) is excavated longitudinally along a chamber surface (2) in the rice fields with spacing of 150 to 180cm between ditches and depth of 30 to 40cm; then a ridge (3) is made on each chamber surface with height of 10 to 15cm and width of 20 to 25cm; a small pit is shallowly dug on the ridge by a spade, and the root of a rape seedling (4) is put in the pit sideways, then the root collar of the rape seedling is slightly compacted by using small soil clods and the root is covered half open by using soil or soil clods, and the rape seedling is transplanted to the ridge. The method of the invention moderately increases the density and depth of furrowing; by using the chamber surface as the ridge and putting the rape seedling root in the pit sideways, the distance between the planting root zone of the rape and water surface is increased and the subsurface waterlogging of the rape seedling is relieved; covering the root of the rape seedling half open by using soil or soil clods, large pores are generated artificially, thereby oxygen in the oil is increased; the better compatibility between moisture and oxygen can lead to very good growth of the rape seedling, and increase the survival rate of the rape seedling, as well as the economic benefits of the cultivation and planting of rape.

Description

Technical field: [0001] The invention relates to a method for transplanting rape in a paddy field with poor drainage, belonging to the technical field of agricultural cultivation. Background technique: [0002] There are two methods of field production of rapeseed: direct seeding and transplanting. Live planting is to sow seeds directly into the field. Its process is simple and requires less labor per unit of land area. It is mainly used in areas with few people and a lot of land. Since direct seeding is difficult to ensure the necessary conditions for robust growth of rapeseed, it is difficult to achieve uniform seedlings and balanced growth, so the yield per unit area of ​​direct seeding cultivation is generally low. Due to the seedling raising process, transplanting planting can cultivate seedlings in an artificial environment to ensure the healthy growth of early seedlings. Although it requires more labor than direct seeding planting, it has a higher yield and is suitab...

AI Technical Summary

Problems solved by technology

For paddy fields with poor drainage, if transplanted according to the current method, the rapeseed seedlings will be severely waterlogged, and the number of green leaves will also decrease rapidly.
