What are the three-line rice varieties?
The breeding of three-line rice can be said to be the real beginning of the utilization of rice heterosis in China. As early as 1973, Yuan Longping's team cultivated a strong heterosis combination "Nanyou 2". At the same time, the "three lines" of wild abortive indica hybrid rice in China were completed.

Guangxi takes the lead in breeding three-line male sterile lines of aromatic red rice
Recently, the Science and Technology Department of Guangxi Autonomous Region organized relevant experts to carry out field technical identification on the wild sterile line Areca Red A bred by Xiangzhou Huangshi Rice Research Institute. After strict field investigation and indoor microscopic examination, and after listening to the technical report and answering questions of the breeder, the expert group identified that Areca Red A reached the standard of rice three-line sterile line, which was the first aromatic red rice three-line sterile line bred in China, with strong innovation. Areca red A has stable agronomic characters, stable sterility, good flowering habit, better rice quality and high resistance level

Control techniques of "two Diseases and three pests" in Rice
Rice two diseases and three insects refer to rice blast, sheath blight, rice stem borer, rice planthopper and rice red spot black foam cicada, which do great harm to rice and should be prevented and controlled. Rice blast is caused by long-term irrigation of deep water or excessive drought and partial application of nitrogen fertilizer. There are three susceptible stages in rice life, namely, seedling stage, heading stage and heading stage. Panicle neck blast has the greatest effect on rice yield, which should be prevented as early as possible at break stage and full heading stage. Rice blast is divided into seedling blast, leaf blast, node blast, panicle blast and grain blast. Rice blast

The problem of "three controls" fertilization for growing Rice
The technology of three-controlled fertilization for rice is aimed at the outstanding problems in rice production, such as excessive application of chemical fertilizers and pesticides, unstable yield, low fertilizer use efficiency, serious environmental pollution and so on. efficient and safe fertilization and matching characterized by fertilizer control, seedling control, disease and pest control (referred to as three controls)

How to control the three major diseases of rice?
How to control the three major diseases of rice? Please introduce the control methods of the three major rice diseases can refer to the following methods for control: 1. Rice blast (1) Leaf blast: dark green, nearly round or oval spot, followed by a slight tip at both ends; usually when there are acute spots or disease centers, especially when nitrogen fertilizer is applied.

Apply the "three fertilizers" of rice well
Seedlings flourish, invalid tillers grow rapidly, resulting in greedy green late maturity; some seedlings grow shade, leading to diseases such as sheath blight or rice blast. If fertilizer damage occurs in rice fields, the yield will be reduced in light cases, and the seedlings will be ploughed and replanted in heavy cases. In order to give full play to the fertilization effect of rice, in addition to applying sufficient base fertilizer, we must apply "three fertilizers" in topdressing, that is, tillering fertilizer, panicle fertilizer and grain fertilizer. Rice fertilization should be considered comprehensively according to variety characteristics, soil fertility, climatic factors and cultivation conditions, and applied flexibly. The demand for fertilizer for rice is shown in the camp.

Water Management measures of "three rows and three Irrigation" for Rice
One, three and one row: from the critical tillering stage to the tip stage of the second leaf (20 days before heading), the field should be drained to control the growth of ineffective tillers. The grass seedlings should grow vigorously, and the fields with dark green leaves, fertile fields and cold-soaked fields should be heavily exposed to promote the fading of their leaves; for the fields with poor growth of grain seedlings and thin fields, the fields with low groundwater level should be exposed to the sun for many times, and the best degree is not to sink the feet in the field. The second row: the second drainage was carried out from 5 to 7 days before heading to the heading stage, so as to improve the root activity and enhance the nutrient absorption capacity of rice roots.

National standard for japonica rice
According to the national standard, japonica rice is divided into one, two, three, four and six grades. Among them, the lowest quality index of first-grade early japonica and japonica glutinous rice is 81%, impurities 1%, and the color and smell should be normal. The lowest quality index of the roughness rate of late japonica rice in the first class area is 82%, and the second class is the second class.

Rice "three Fertilizer" and its Application skills
Scientific fertilization is one of the important measures to achieve high quality and high yield of rice. However, rice fertilization is a highly technical work, which must be flexibly mastered in practice because of variety characteristics, soil fertility, climatic factors and cultivation conditions. As we all know: the demand for fertilizer of rice is shown in the nutrition period, the nutrition critical period and the nutrition maximum efficiency period. For example, the growth period of early rice is short, the amount of fertilizer required is relatively less, and fertilization should be early and concentrated. If the growth period of middle rice and late rice is longer, the amount of fertilizer required is large, and the absorption intensity is high, topdressing should be increased.
