Dry-sowed waterpipe seedling culture method

Abstract

The invention discloses a dry seeding water pipe seedling raising method which comprises following steps: a. making box beds, making box ditches, and making side ditches; water discharging of paddy field, making box beds, making box ditches and making side ditches are carried out within ten days at the solar term of slight snow of last year, the width of the box beds is 150 to 160cm, the width ofthe box ditches and the side ditches is 30 to 35 cm, the depth of the box ditches and the side ditches is 20 to 35cm, and the water depth of the box ditches and the side ditches is 7 to 10cm; b. application of base fertilizer; slag fertilizer is applied on the box beds by 1 to 1.5cm of thickness within five days at spring begins of the year; c. steeping seeds; d. seeding; the seeding is carried out at the day of application of base fertilizer according to 40 to 50g / m<2>; e. making film greenhouse; f. piping water; g. transferring seedling; seedlings are transplanted to the field at the time between lunar clear and bright and grain rain of the year. The invention has the advantages that the seedling age is prolonged; the seeding can be brought forward 20 to 30 days; the seedling raising time is prolonged by 5 to 15 days; the millet flowering time is before summer drought; the millet harvest time is brought forward by 10 to 15 days; the rice yield is increased by 25 to 50kg per mu.

Description

technical field [0001] The invention relates to a rice cultivation method, in particular to a rice seedling raising method, and more particularly to a dry sowing water pipe seedling raising method. Background technique [0002] Hybrid rice has successively adopted steam seedling raising, warm seedling field seedling raising, paddy field film seedling raising, dry land film seedling raising, and now warm moist seedling field seedling raising is generally used. The so-called warm seedling field raises seedlings, which is to make box beds, box ditch, and side ditch in the paddy field within 5 days before the Lunar Awakening Festival. The box ditch is 25cm deep, and the depth of water in the ditch is 5-9cm. Sow hybrid rice seeds within a day. After sowing, insert arches with bamboo blocks and cover with film. Pay attention to management at ordinary times. , plant the seedlings in the seedling field to the field. The main defects in the existing methods of raising seedlings in ...

AI Technical Summary

Problems solved by technology

The main defects in the existing methods of raising seedlings in warm and moist seedling fields are as follows: one is that the sowing period is late, and when the millet blooms, it is often in the summer drought period, which seriously affects the yield of rice; It takes 10 days to start threshing, which will affect the cultivation of late rice or the growth of ratooning rice; the third is that the seedlings have weak hairpin
