Dry-land rice seedling raising method

Abstract

The invention relates to a dry-land rice seedling raising method and belongs to the technical field of crop cultivation. The dry-land rice seedling raising method is characterized by including steps of flattening and fertilizing soil of a seedling bed before sowing seedling seeds; ridging and ditching the seedling bed; moving the soil 1-2cm in thickness onto the upper layers of ridges of the seedling bed, and paving a net type plastic product (3) on the seedling bed, and paving the moved soil onto the ridges of the seedling bed; uniformly sowing the seedling seeds onto the seedling bed; watering the seedling bed in advance according to water retention conditions of the soil when a seedling (1) is transplanted; lifting the seedling (1) on one side of the seedling bed by pulling force of the net type plastic product (3), and lifting the seedling (1) on the other side of the seedling bed by the same method. The seedling raising method is capable of sufficiently stretching roots of the seeds, normal growth of the seedling (1) is unaffected, and damage to the seedling (1) is low during seedling lifting; meanwhile, labor intensity in seedling lifting is alleviated, and the dry-land rice seedling raising method has the advantages that cultivation of strong seedlings is facilitated, using cost is low, seedling lifting effect is good and operation efficiency is improved.

Description

Technical field: [0001] The invention relates to a method for raising seedlings in dry land, belonging to the technical field of crop cultivation. Background technique: [0002] Seedling dry cultivation is to sow the seeds on the seedling bed, carefully manage them, and then transplant them to the field after a certain period of time. Because seedling raising is carried out in dry land, the oxygen in the soil is relatively rich, the temperature of the soil is high, and the mineralization speed of nutrients is fast, which is very beneficial to the growth of seedlings. Therefore, dry seedling cultivation has become a method that is widely used at present. . Because the seedlings are grown in the dry land, after growing for a certain period of time, along with the gradual elongation of the root system of the seedlings, the influence of plant injury caused by the process of pulling out the seedlings for transplanting the seedlings is also gradually increased. Before the seedli...

Problems solved by technology

Before the seedlings are transplanted, although people can reduce the impact of seedling injury by watering, moistening and softening the soil, shortening the young age, and paying attention to the method of pulling out the seedlings, the effect is still very limited.

Although watering before seedling transplantation can soften the soil to a certain extent and reduce the soil resistance when pulling out seedlings, it is still difficult for the stems of young seedlings to adapt and bear the exertion of force on young stems of rice seedlings when people pull out seedlings, and it also increases Reduce the difficulty of operation for the operator; although shortening the young age can reduce the length of the seedling root system growth and have a certain effect on the uprooting of the seedlings, it is not conducive to the normal growth of the seedlings in the seedling field, and brings certain negative effects on the growth of the seedlings after they are transplanted to the field. impact, increasing the difficulty of obtaining high yields
