Field Management of jointing and long panicle stage of planting Rice
Rice jointing begins around the peak tillering stage and does not stop elongation of internodes until a few days after heading, which is called jointing and panicle stage. The goal of field management at jointing and heading stage is to promote strong stems, large ears and prevent apprenticeships on the basis of protecting tillers and increasing ears.

Intensive cultivation techniques for Super High yield of growing Rice
1. Compared with the traditional high-yield cultivation techniques, the rice super-high-yield intensive cultivation technique system has the following characteristics. 1. Young seedlings should be planted early. Intensive cultivation techniques can transplant 3-leaf-old seedlings of 2Mel in winter fallow fields or winter paddy fields, and 5-leaf seedlings of 3Mel in two-season fields.

Control of drillworm in growing rice
Netizen Yeshan Judicial Office sent an email on July 4: I am a staff member of the town agricultural station, and now we have too many rice heart worms here, which is difficult to treat! I asked farmers to use wild killing and dimethoate, and the results showed that the effect on the control of heart worms was poor. Excuse me, what method should be used for prevention and control?

Control of Purple sheath Disease in growing Rice
After heading, the flag leaf sheath produces dense needle-tip-sized purple dots on the flag leaf sheath, which gradually extends to most of the leaf sheath or the whole leaf sheath turns purple-brown, especially in the outer wall of the leaf sheath, sometimes infecting the inner wall or deep into the stem, and the seriously affected flag leaves are early.

Control of Drosophila melanogaster in growing Rice in Philippine Island
The scientific name Hydrellia philippina Ferino belongs to Diptera, Muscidae. Hairy-eyed water fly is a general term for harming rice water flies. In addition to Oriental hairy-eye water flies, there are many kinds of water flies, such as gray thorn water flies, rice water flies (Ephydra macellaria Egger) and so on. Five species have been found all over the world, with similar morphology.

Control of Bad Seedling Disease of growing Rice
Symptoms: after the occurrence of evil seedling disease in rice, the internodes of the diseased plants elongate, grow thin and tall, the plant color is lighter, the leaves are narrower than the normal plants, there are indefinite fibrous roots inside or outside the leaf sheath on the nodes, and there are white molds in the rice stalk, which turn reddish and sometimes turn reddish.

Prevention of lodging, premature senility and greed in the late growth stage of planting rice
The abnormal phenomena such as lodging, premature senility and greed for green of rice are due to improper selection of varieties or some unfavorable factors in the process of rice growth and development, which are inconsistent with the normal growth of rice cultivation objectives. it seriously affected the yield and quality of rice.

The "five precautions" should be done well in the later stage of growing rice.
Rice entering the late growth stage is a critical moment for the formation of yield, so we must do a good job of the following five precautions. 1. For the fields with no nitrogen fertilizer in the middle stage and premature senescence in the later stage, 2kg urea per mu can be applied as break fertilizer in the break period. Yeah, grow normally and be strong.

Prevention of Diseases in Seedling stage of planting Rice
First, symptoms of blight: in the seedling stage, sometimes the buds change color, the leaves are locked, and finally die, spreading very quickly. Control measures: the pathogen of blight survives in the soil, and the occurrence of blight is related to climate, seedbed temperature, soil pH, fertilizer and other environmental conditions.

How to reasonably determine the amount of nitrogen Fertilizer in accurate quantitative cultivation of Rice
The quantification of nitrogen needs to consider the law of fertilizer requirement of high-yield rice, the law of soil nitrogen supply, the characteristics of fertilizer and the utilization rate of fertilizer in the current season, as well as the changes of various conditions during the growth period, including total nitrogen quantity and nitrogen application method. Determination of total nitrogen: obtained through soil testing, formula, etc.

Key points of cultivation in the late growth stage of planting Rice
Pest control: disease: the main disease that needs to be paid attention to in the later stage of rice growth is rice blast. We should seize the opportunity to apply 2 Murray 3 times after heading, and the interval is about 7 days. About 100 grams of tricyclazole wettable powder can be used per mu, and 30 kilograms of water can be sprayed on leaves.

Three key periods should be paid attention to in planting rice film and raising seedlings.
According to many years' practical experience, I think that the technology of raising rice seedlings with thin film should pay attention to three key periods: closed period, refining seedling stage and film opening stage. The first period: the closed period, that is, from sowing to the stage of one leaf and one heart. During this period, the film should be tightly closed and created.

Why is it necessary to dry rice before sowing?
Rice seed drying before sowing can effectively improve seed germination rate and germination potential, the main reasons are: 1. Seed drying can promote seed ripening and improve enzyme activity.

Storage methods of Peanut Seeds
First, the seeds should be fully dried before storage, so that the water content of the seeds is reduced to less than 8%. According to the experiment, when the seed water content is less than 8%, the storage is very safe, even at-25 ℃, it does not affect the germination power. When the water content of the seed is higher than 10%, the respiration is enhanced and released.
