Fertile-seedbed dry-seedling-raising method for rice

Abstract

The invention discloses a fertile-seedbed dry-seedling-raising method for rice. The method comprises steps as follows: (1) seedbed selection and treatment; (2) nutrient soil preparation; (3) seedbed production; (4) seed selection and treatment; (5) seeding; (6) seedbed management. Compared with existing rice seedling raising technology, the method has the advantages that the fertile-seedbed dry-seedling-raising method for the rice is used for seedling raising, seedling raising is performed on dry land directly, so that seedbeds, fertilizer, water and labor are saved processes of cold resistance, drought resistance and sterilization are omitted, and the seedling raising cost is greatly reduced; besides, seedlings obtained with the fertile-seedbed dry-seedling-raising method for rice is high in quality, that is, the emergence rate is high, seedlings are robust, green turning and living are fast, the carbon content and the nitrogen content are higher, the rooting ability is higher, and thus the subsequent yield per mu of rice is increased.

Description

technical field [0001] The invention relates to a rice seedling raising method, which belongs to the technical field of rice cultivation and planting. Background technique [0002] Rice is native to tropical Asia. After being widely planted in China, it gradually spread to all parts of the world. According to different classification methods, rice can be divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice; It is later called rice or rice. Nearly half of the world’s population eats rice. There are various ways to eat rice, including rice, rice porridge, rice cakes, rice cakes, rice noodles, etc. In addition to being edible, rice can also be used to make wine. , sugar as industrial raw materials, rice husk, rice straw also has many uses. At present, there are many methods of raising rice seedlings, but the quality of seedlings is not high, and the survival rate of transplanted seedlings cannot be further improved. Im...

AI Technical Summary

Problems solved by technology

At present, there are many methods of raising rice seedlings, but the quality of seedlings is not high, and the survival rate of transplanted seedlings cannot be further improved. Improper cultivation methods restrict the increase of rice yield; During the period, the bad seeds, rotten buds of rice, and the occurrence of various diseases and insect pests of rice caused a significant reduction in rice production and affected the normal income of farmers.
