According to different methods, rice can be divided into indica and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Chinese scientist Yuan Longping has made great contributions to the research of hybrid rice and is known as the "father of hybrid rice".

The rice grains produced by rice are called rice or rice after they are hulled. Nearly half of the world's population feeds on rice. There are various ways to eat rice, including rice, rice porridge, rice cakes, rice cakes, rice noodles, etc.

<> rice is a cereal crop of rice, and the seeds of rice are rice, and the rice is called brown rice after removing the glume husk, and the brown rice is milled to obtain rice from the rice bran layer. Nearly half of the world's population depends on rice as its staple food, and in addition to being edible, rice can also be used as a raw material for making wine and sugar, and rice husks and rice stalks can be used as livestock feed. The main rice-producing areas in China are mainly Northeast China, the Yangtze River Basin and the Pearl River Basin.

Rice is a direct cash crop, and rice is the staple food of residents in Northeast China and South China.

Rice is a grassaceae.

Rice is a plant of the genus Rice, native to China and India, and its seeds are rice.

After the rice is hulled, it is called brown rice.

Brown rice is the staple food of half of the world's population, and rice is suitable for growing in a high temperature and humidity environment, and it is not strict with the soil.

1. Variety introduction

Rice is an annual herbaceous plant of the Poaceae family, with a height of rice, and its shape varies depending on the variety, and the leaves of rice are lanceolate, and its flowers are conical.

The length is about 30 cm, and 200-300 rice flowers will bloom on one ear of rice, and one rice flower will form a grain of rice.

2. Growth environment

Rice is suitable for growing in a high temperature and humid environment, the best germination temperature of its seedlings is 10-12 degrees, and the most suitable growth temperature is 28-32 degrees, and after rice heading, the environmental temperature needs to be kept between 25-35 degrees, which is conducive to the vigorous growth of plants, and if the temperature is lower than 20 degrees or higher than 40 degrees, it will affect the pollination of rice.

3. Fertilization management

When cultivating rice, it is necessary to apply plant ash to the soil 10-15 days before sowing.

Or chicken and duck manure to improve the fertility of the soil and promote the healthy growth of rice, and during the rice tillering period, it is necessary to apply nitrogen, phosphorus and potassium compound fertilizer to it, and spray potassium dihydrogen phosphate on the leaves of the plant.

Increase the yield of rice.

4. Maintenance method

When maintaining rice, it is necessary to pull out the weeds in the soil in time to avoid weeds and rice robbing of nutrients, and to regularly observe the growth of rice, if it is found that there are snails in the rice field.

and other pests, it is necessary to spray insecticides according to the instructions to eliminate pests and make rice grow healthily.

1. Rice is a cereal crop of rice, which is one of the main food crops in the world.

2. Rice is divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice according to rice type; According to the way of seed retention, it was divided into conventional rice and hybrid rice; According to whether soilless cultivation is divided into paddy field rice and floating rice; According to the survival of the celery cycle, it is divided into seasonal rice and "lazy rice" spring (regenerative rice in more years); According to the height of the rice, it is divided into ordinary rice and giant rice.

Rice is divided into six parts: roots, stems, leaves, flowers, fruits, and seeds. Among them, the stem of rice is generally cylindrical, hollow, there are nodes on the stem, the leaves are born on the nodes, the upper and lower nodes are called internodes, there are 7-13 internodes at the base of the stem that are not elongated, called the tillering nodes, and the upper part of the stem has 4-7 obvious and elongated internodes to form a stalk; The leaves are alternate on both sides of the stem, which is 1 2 leaf inflorescences, and the number of leaves on the main stem is consistent with the number of stem nodes, and the number is directly related to the variety and growth period. That's about it.
