Seedling raising technology for paddy rice in small field pools in mountainous area

Abstract

The invention relates to a seedling raising technology for paddy rice in a small field pool in mountainous area. The seedling raising period in the small field pool is set to be 28, March to 8, April, early seedling raising is performed in low elevation areas and late seedling raising is performed in high elevation areas. Before seedling raising, seeds are dried in the sun for 1 to 2 days, then 4 percent of saline solution is used for picking out imperfect grains, perfect grains are socked for 48 to 52 hours after being cleaned by using water, accelerating germination for 24 to 48 hours is performed after fishing out, and the length of bud does not excess half grain. The small field pool is digged to be the field pool with the depth of 13 to 15 cm and the width of 80 to 100 cm, and the pool length is 1.5 m which is in accordance with that of large field of 667 square meters. A layer of fine sand, with the thickness of 1 to 2 cm, is evenly paved on the bottom of the field pool, then fertile soil and fine sand are mixed according to the ratio of 1 to 1 and compressed for 4 to 5 cm, thoroughly decomposed light liquid dung is used for pouring, the seeding is evenly broadcasted, then fine fertile soil with the thickness of 0.5 cm is used for covering, and double-film covering is adopted for warming. Unit area high yield is achieved through field pool seedling management and plantlet insertion nursery period rich water management such as warming for accelerating germination, insulating seeding promotion insulating for seedling growth promotion, film uncovering for domestication, and rat and bird damage prevention, as well as comprehensive technology such as large field early transplanting in optimum periods, formulated fertilization, cultivation, weeding, extermination of disease and insect pests.

Description

technical field [0001] The invention relates to a seedling raising technology in a small ground pond in a mountainous area. Background technique [0002] The rice seedling raising technology in mountainous areas has been continuously innovated through water seedling raising, mud falling valley, film raising and dry seedling raising, and plastic floppy disk water management seedling raising. But all there is operation more complicated, be difficult for management, use kind amount big, the production cost height, the seedling-forming rate is low, the shortcoming of poor seedling quality. Later, the innovative two-stage seedling raising in the greenhouse basically solved the above problems, but there is still a need to build a seedling raising greenhouse specially for centralized management. Farmers need 12 yuan for raising seedlings per kilogram of seeds, and the heating of the greenhouse requires a lot of fuel, which emits a lot of emissions when burning. carbon dioxide. Th...

Problems solved by technology

[0004] The purpose of the present invention is to propose a technology for raising rice seedlings in small ground ponds in mountainous areas, which can solve the problems in the current conventional seedling raising technology, such as large amount of seeds, concentrated labor, small elasticity of seedling age, heavy rotten seedlings, low survival rate of seedlings, and poor quality of seedlings , technical problems such as the weight of changing clothes when transplanting into a large field, and slow seedling emergence and tillering
