What is Rice? What is the difference between rice and rice

Rice is a cereal crop of the genus Rice, and the representative species is rice. Rice is native to China and India, and 7,000 years ago in the Yangtze River basin of China.

The ancestors used to grow rice.

Rice is pressed by paddy.

The types are divided into indica and japonica rice.

Early rice and middle and late rice, glutinous rice and non-glutinous rice. According to the way of seed retention, it is divided into conventional rice and hybrid rice.

There are other classifications, which are divided into paddy rice and floating rice according to whether they are soilless or not; According to the life cycle, it is divided into season rice and "lazy rice"; According to the height, it is divided into ordinary rice and giant rice of about 2 meters; According to salinity tolerance, it is divided into ordinary fresh rice and "seawater rice."

There is no difference between rice and rice. Rice is a botanical term, and rice is the rice that has been husked. After the rice is harvested, it is dried in the sun for 2-3 days, the rice is dried, the impurities such as the deflated rice are removed, and the grain is divided by electric grain splitter, windmill or manual shaking, and the full and heavy rice is automatically screened out by the wind, and then the rice mill is used to remove the chaff, which becomes rice.

Precautions for planting rice.

Pay attention to the choice of rice seeds: if you want to increase the yield of rice, the first choice should also look at the rice seeds, the quality of the fields selected by different rice varieties is not the same, according to the actual situation of the rice field at home, it is not necessarily expensive is good, only suitable is the most important.

Rice is a food crop that is an important food ration for Chinese, especially in the southern regions.

Rice is the fruit that grows from rice (called Yingguo), and after processing, the husk is removed, and the rice grains left behind are called rice.

Rice refers to the period from rice planting to the pre-harvest period.

Rice refers to the food obtained from the fruit of rice, which is dried in the sun and machine-milled.

Rice is wheat that has not yet been harvested, and rice is bagged rice that has been processed.

Rice is relative to upland rice, upland rice produces millet that is very similar to rice, but the yield is generally lower, and the rice is slightly smaller, rice is planted in paddy fields, and upland rice is planted in the ground.

The difference between rice and millet is that rice is larger than millet, millet is smaller than rice, rice is white oblong, millet is yellow and round and very small. Rice is white (there are also classifications such as fragrant rice and black rice), millet is yellow (there are also classifications such as black rice and small white rice), rice is negative, millet is positive, in short, different rice has different tastes and nutrients.

Rice is a finished product made of rice after cleaning, hulling, milling, and finishing the finished product. It is used to make white rice and is a staple food in the south.

Millet is also called corn, is a dryland crop, is yellow, made of small rice is very fragrant, golden, its ** is generally 2-3 times that of rice, is a kind of miscellaneous grain.

The former refers to the rice produced by rice, and the latter refers to the rice plant. Actually, there is no difference in essence.

Rice, also called rice or rice, is an edible grain, an annual herbaceous plant, which likes temperature and humidity, and is commonly known as "rice" or "millet" in southern China, and the hulled grain is rice.

The difference between rice and rice is that neither species grow in the same environment, one grows in land soil and the other grows in water, but both are food that people depend on for survival.

After the rice is harvested, it is the rice, and it is a progressive process.

Rice is commonly known as rice. It's the rice we eat. It is processed by a rice mill from the ears of rice.

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.

<> 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.

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 is 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 one of the important food crops for human beings. Rice has a long history of cultivation and consumption. Half of the world's population consumes rice, mainly in Asia, southern Europe and parts of tropical America and Africa.

The United Nations designated 2004 as the International Year of Rice, the third largest producer of rice in the world, lower than maize and wheat, but capable of sustaining a larger population.

An important marker of the beginning of reproductive growth in riceThe spikelet differentiation stage is one of the most important periods in the life of rice, which includes the jointing stage and booting stage. After the beginning of panicle differentiation, rice enters the period of human vegetative growth and reproductive growth. During this period, the growth of plants increased rapidly, the leaves grew one after another, the growth of roots at the end of differentiation reached the maximum value in a lifetime, the leaf area of the whole field also reached the highest peak, and the accumulation of dry matter of plants was nearly 50% of the total dry matter, so it was also the period when rice needed the most fertilizer in its lifetime.

It has been determined that the absorption of nitrogen, phosphorus and potassium accounts for about 50% of the total absorption in a lifetime. During this period, not only do you need a lot of mineral nutrients, but you are also very sensitive to the conditions of your surroundings.
