Method for raising seedlings of rice

Abstract

The invention relates to a method for raising seedlings of rice. The method comprises the following steps: step 1: seed soaking and germination; step 2: sowing; step 3: darkening processing; step 4: management of temperature and humidity in a greenhouse; step 5: management before transplanting. The method for raising seedlings of rice has the following beneficial effects: matrixes made by cassava leftovers during alcohol production are fully used so that production cost is greatly reduced; the matrixes are good in water storage performance and water retention performance so that moisture management during the process of raising seedlings is simplified; the method is easy to operate, manage and labor and time-saving; seeding trays are good in consistency with white root hair and robust seedlings; during transplanting, missing and breaking of seedlings are avoided; and the survival rate of seedlings is high.

Description

technical field [0001] The invention relates to a rice seedling raising method, in particular to a method for realizing mechanized rice seedling raising by using a substrate in a greenhouse. Background technique [0002] The quality of rice seedling raising is an important factor in determining rice yield. Strong seedlings with well-developed roots and tall branches and leaves represent the inherent advantages of rice growth and are an important guarantee for stable and increased production. my country is a traditional rice producing country, and there is a great demand for strong rice seedlings. [0003] Although the traditional rice paddy seedling raising method in the field can produce strong seedlings that meet the requirements of machine transplanting, it has the following defects: ① seedling raising and raising seedlings are labor-intensive, causing great harm to people's bodies, and with the development of my country's economy, labor costs It is getting higher and hig...

Problems solved by technology

[0003] Although the traditional rice paddy seedling raising method in the field can produce strong seedlings that meet the requirements of machine transplanting, it has the following defects: ① seedling raising and raising seedlings are labor-intensive, causing great harm to people's bodies, and with the development of my country's economy, labor costs It is getting higher and higher, which is not economically suitable; ②It is difficult to guarantee the quality of seedlings, which is greatly affected by the external climate environment. If continuous low temperature and rainy conditions are encountered during seedling raising and sowing, there will be problems of uneven seedling emergence and low seedling emergence rate; ③Planting Seedlings are limited by the weather. If there is continuous rainy weather, the seedling boards cannot be transported and planted, which will affect timely planting

However, because of its low calorific value, combustion needs to be thoroughly dried before use, the cycle is long, and the value is low, thermal power plants and other units are reluctant to use it; Potassium and other nutrients are low, and farmers are not enthusiastic about using them

Therefore, the problem of disposal of cassava waste from alcohol production has not been solved
