Simple diagnosis and Control of "withered Heart" in Rice
1. Simple diagnosis of rice "withered heart" 1. A "withered heart" caused by pests. Chilo suppressalis, Chilo suppressalis and mole cricket can all cause "withered heart". The main differences are as follows: (1) Chilo suppressalis: large wormhole, many insect feces, and feces are generally arranged between rice leaf sheath and stem. The stem, leaf sheath and leaves of the killed rice turned yellow. The harm is more serious at the edge of the rice field and lighter in the middle of the field. (2) Chilo suppressalis: after hatching, the young borer first gathered on the inside of the rice leaf sheath to feed, and water-stained macula appeared on the outside of the damaged leaf sheath, and then gradually yellowed.

How to control the "early panicle" of rice?
The Yangtze River and Huaihe River basins have continued to suffer from drought and little rain this year, which has seriously affected agricultural production. From July to August, the phenomenon of early panicle appeared in the rice planting areas north of the Yangtze River and in the Huaihe River basin. The performance in the field showed that the early heading of each hole was 2mur3 ears, which was different from the late tillering for more than 7-10 days, obviously showing "two ear" or "three ear". To make up for the loss of field production caused by "early spike" as soon as possible, the following analyzes the causes of early spike and puts forward rescue measures. The length of rice seedling age is closely related to the phenomenon of early panicle.

The goal of rice is to cultivate roots, protect leaves and promote tillers.
Wang Shengxuan, an associate researcher at the Food and crop Research Institute of the Provincial Academy of Agricultural Sciences, believes that when the rainy season enters every year, there will be regional heavy rainfall in the north and south rice regions of our province, causing flooding in some areas, especially rice planted in relatively low-lying paddy fields. Some rice seedlings are not topped. After flooding, the roots and leaves of rice were seriously damaged, the normal physiological metabolism and stress resistance of the plant were seriously weakened, and the number of total tillers decreased seriously. If the flooded rice fields are not managed timely and effectively, the yield will be greatly reduced, or even no harvest. Therefore, scientific remedial measures should be taken in time for the flooded rice fields.

Post-disaster management and protection of flooded rice
In view of the serious damage of roots and leaves and the serious decline of total tillering seedlings after rice flooding, measures should be taken to raise roots, protect leaves, promote tillers, increase panicle rate, compete for grains and increase weight. Drainage of stagnant water in the field as early as possible, squatting seedlings in the open field, in order to improve the physical and chemical properties of the soil and eliminate toxic substances. For the fields that have been submerged for a long time, the overcast and rainy weather can drain water at one time; in the hot sun and high temperature weather, it is appropriate to gradually dehydrate, first let the upper part of the rice plant out of the water, dehydration and air regulation at night, daily irrigation and night dew, so as to facilitate the recovery of rice growth. two。

Four precautions for harvesting rice
Attention should be paid to the following four points before and after rice harvest. 1. Drainage as early as possible. Drain the paddy fields as much as possible, and dig trenches to dry the lowlands as early as possible if necessary. two。 Ripe for harvest. Manual harvesting is carried out when more than 95% of the rice glumes in the field turn yellow, the grains harden and the grains are transparent. Mechanical harvesting can be appropriately delayed by a few days. 3. Pay attention to the way. Artificial cutting and drying can increase 1000-grain weight and yield, and at the same time, rice has good marketability and high germination rate. Harvest with a harvester, the most

The latest Rice breeding techniques in the World
The purpose of the study on salt-tolerant rice breeding is: 1. To make the new salt-tolerant rice adapt to the cultivation of saline-alkali soil. 2. In the case of shortage of fresh water, seawater can be fully utilized for irrigation. Salt-tolerant crops such as tomato, melon and barley have been reported abroad. Salt-tolerant rice cultivated by the University of Sussex in the UK can grow vigorously in the field, but we must see the complexity of regulating salt content in the field. Genetic engineering of salt-tolerant rice is very active in the UK. Researchers use genes of salt-tolerant rice to be implanted into rice.

What is an improved variety of rice? How to select improved varieties according to local conditions?
Improved rice varieties have relatively stable specific heredity and relative consistency in biology, economy and morphology. In specific areas, specific cultivation conditions and periods, it meets the needs of production in terms of yield, maturity, quality and adaptability. In addition to having the basic conditions of varieties, improved rice varieties must also have the advantages of high yield, stable yield, good rice quality, disease resistance, insect resistance, strong stress resistance and so on. A good rice seed should include three aspects: first, it should have high yield, high quality,

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.

Raw gypsum powder can control physiological bacterial blight of rice
Rice physiological bacterial blight often occurs in cold soaked fields in Shanchong and unripe paddy fields with organic green manure. The disease often occurs at the tillering stage of rice, which shows that there are few tillers of rice, the leaves turn yellowish brown, and there are irregular tea brown spots on one or two leaves at the base, and some are mistaken for leaf rice blast. Pull out the grass, the root system is yellowish brown, the heavy is black, and the seedlings are not long, as the saying goes, "Fa Qiu". There are three main reasons for the occurrence of physiological red blight: first, toxic substances such as hydrogen sulfide are produced during the decomposition of green manure; second, some cold soaking
