Problems solved by technology

[0004] Most of the existing rice planting is directly sown to the field in the early stage. This method has a very low rice yield. In many places, the seedlings will be raised first, and then the seedlings will be transplanted to the field. However, the existing seedling raising methods are complicated and the seedling raising effect is not good.

Embodiment 1

[0019] A method for cultivating rice seedlings, comprising the following methods:

[0020] (1) Select the base field and complete the base field: choose the loess soil with good ventilation and high nutrient content, plow the land 30-40cm deep, then level the land with a plow and rake, and pour water into the field. 5-7 days;

[0021] (2) Covering improved soil: The formula of the improved soil is 45kg of mud at the bottom of the pond, 10kg of bean curd residue, 8kg of poultry manure, 8kg of rapeseed cake powder, 3kg of distiller's grains, and 3kg of reinforcing material. The raw materials are fully mixed, and the improved soil is evenly covered On the base field after the step (1) treatment, the thickness of the improved soil covered is 1-3cm, and the natural ventilation is 1-2 days;

[0022] (3) Seed selection and sowing: select plump and high-quality seeds, place them in the sun for 3-5 hours, then soak them in rice washing water for 6 hours, take them out and soak them in...

Abstract

A rice seedling cultivation method includes the following steps of basic field selection, basic field preparation, improved soil covering, seed selection, sowing, heat preservation, topdressing and transplanting. The cultivation method is reasonable and simple, time for seed selection and fertilizer application during cultivation is controlled accurately, fertilizer is properly applied, nutrient components and disease resistance and drought resistance of seedlings are effectively improved, and the method has good functions in later seedling growth and development, rice yield increase and increase of rice starch content.

Description

technical field [0001] The invention relates to the field of rice seedling cultivation, in particular to a rice seedling cultivation method. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest kind of grain in Oryza genus. It is also called Asian cultivated rice, and it can be said to be rice in simple terms. It is an annual, gramineous plant, monocotyledonous, sexually warm and humid, about 1 to 1.8 meters high when mature, with slender leaves, about 50 to 100 cm long and 2 to 2.5 cm wide. The flowers of rice are very small. When blooming, the main flowering branches will be arched, and small flowers will bloom between 30 and 50 cm below the branches. Most of them are self-pollinating and set seeds, which are called rice spikes. Generally, the size of the rice ear is 5 to 12 mm long and 2 to 3 mm thick. [0003] Rice is one of the world's major food crops. China's rice sowing area accounts for 1 / 4 of the co...
