Characteristics of Rice What are the characteristics and advantages of rice in planting and selling?

(1) cultivation. The growth period and response characteristics of rice varieties to light and temperature are important basis for variety collocation, sowing date arrangement and cultivation measures.

(2) Introduction. The temperature sensitivity, photosensitivity and basic nutritional growth of varieties must be considered when they are introduced from other places.

(3) Breeding. The first is to identify the light-temperature response of parents, provide ideal parent materials for hybrid breeding, and thus select hybrids suitable for production needs. Secondly, according to the "three characteristics" of different parents, light and temperature treatment or wrong sowing date are carried out to make the hybrid parents bloom at the same time, which is convenient for artificial hybridization. Third, hybrids can be added in different places to speed up the reproduction process.

Rice sales:

The state gives preferential policies to the sale of rice and other grains, but before the state gives preferential policies to the purchase of grain, the prices of various agricultural materials have risen sharply. Therefore, it is uncertain whether all preferential policies are used to increase the economic income of rice farmers. Because there are many uncertain factors in the process of rice planting, management, harvesting and sales.

On the basis of the national grain purchase price, it will drop by 0.05-0.07 yuan/kg, which is basically the grain sales price that rice farmers can really get. For example, the country's rice purchase price this year is 0.92 yuan/kg of the third-class grain standard (it was 0.75 yuan/kg last year). If rice farmers' rice can meet the standard of third-class grain, the actual price of rice sold is between 0.85-0.87 yuan/kg after deducting transportation expenses and impurity moisture. If the quality of the rice you sell is not up to the standard of third-class food, the price will be reduced. With the price difference of per kilogram 1 minute, the average yield of 400 mu of rice operated by each grower is 1200 kg/mu, with a total of 480,000 kg. 1 minute price difference equals 4800 yuan income fluctuation.

Rice is widely popularized because its planting environment is not harsh, and rice is the staple food in most parts of China, which creates a huge market supply and demand. It can be said that high-quality rice is not for sale. The new operation mode of "grain bank" which has sprung up in some places in China has great development space when applied to rice. Rice is a field with great research and investment value.
