1, choose a good species
My county should choose Xiangzaoxian No. 45, Xiangzaoyu No. 32, Zhongjiao 17th, Zhongzao 39, Zhuliangyou 819, Zhuliangyou 189 and other varieties for early rice cultivation or select Y Liangyou 9918 and Zhunliangyou 608 Other varieties for the cultivation of renewable rice.
2. Preparation for childbirth
Choose paddy fields with fertile soil, sunny leewards, high ground and easy drainage and irrigation as a paddy field, and prepare 1:20 per paddy area between paddy fields and Daejeon; prepare 308-hole floppy disks 90 to 100 pieces and 230 to 250 cm long bamboo bows per acre Daejeon. About 30-50 cm wide and about 200 cm long planks or plywood are used to block the buds when planting. Before planting, open the car 2.1 meters in a north-south direction. The surface of the car is 150 centimeters wide (120 centimeters in width and 15 centimeters in width for each side). The turtle is made into a dorsal shape with a width of 60 cm and a depth of 15 cm. The ditch is slightly deeper, so that the drainage is smooth and the rain is dry. When Putian is split, it is necessary to straighten it with a rope. The width of the cabin is uniform and uniform.
3, fine sowing
According to weather forecast, this year's early rice and ratoon rice should be sown on sunny days and sown on March 20-25. The hatchback should be well-prepared 2-3 days before sowing, and the flat surface should be “flat, clean, and meltedâ€. Before placing the plate, use a wooden board to flatten the car into a turtle shape, use one side as a reference to pull the line and place two floppy disks, gently press and level the compacted floppy disk, and try to make the stacking plate and the carton compact so as not to cause the hanging plate to hang. Deadly seedlings. One day before sowing, use a pack of 400 mg of calcium-magnesium phosphate and 100 mg of calcium magnesium phosphate fertilizer. Mix thoroughly and spread into the bottom layer of the dish. (Do not use seed dressing with strong tanning agent, or use strong tanning agent. Mix the fine soil directly to cover the seed), then fill the mud into the floppy disk, and then use a broom to sweep the level of the slurry. Make sure that each hole has about 2/3 of the soil, to prevent string roots and less muddy. The mud in the floppy disk should not be too thin. When it is too thin, it should be delayed until the next day when the slurry is deposited. Early rice cultivation uses 5 to 6 kilos of hybrid rice or 13 to 15 kilos of conventional rice, 4-5 kg ​​of hybrid rice for hybrid rice, and 2-3 ml of imidamine for every 10 kilots of grain. Jin, do a good job of soaking and disinfecting, when soaking, pay attention to the combination of soaking and dehydration, take seeds as enough water to prevent seeds from “injuring waterâ€; hybrid rice seeds promote soaking with 5% of azotoxazole 300 times and promote tillage; Seeds are promoted with the seeds of the rapid pregerminating germination, conventional germination attention to prevent "burning"; seeds more than 80% when the chest is exposed white or sowing, seeding to calculate the amount of each species and floppy disk to determine the sowing volume per car, points Car said, divided into 2 to 3 times evenly sowing and sowing, requiring regular early rice each hole into the seeds of 4 to 6 capsules, hybrid rice each hole into the seeds of 3 to 4 capsules, each ratooning rice Into the seed 2 to 3, try to reduce the seedling rate, lack of hole rate. When planting, use the previously prepared fence to block the side of the car to prevent the buds from being broadcast outside the plate. After sowing, use a broom to gently sweep the buds on the surface of the plate into the hole, and do a good job on the mud. After planting a good seed, apply 100 grams of enemy cough and 30 kg of water to the surface of the planter per acre. After the disk is dry, insert a bamboo arch and cover the film. When inserting the bamboo arch, pay attention to the left and right positions of the sacral plate to prevent the growth of the sapling seedlings. The mulch must be kept clean to prevent affecting seedling photosynthesis. The soil around the membrane should be compacted to prevent it from being blown by the wind and improve the insulation effect. To completely use the intact film, in order to avoid the poor insulation effect caused by rot.
4, Putian Management
Pre-emergence film coverage is maintained strictly, the temperature is controlled within 35°C, and the temperature of the seedlings is controlled to be about 25°C after one leaf. When the weather is fine, it should be lifted at about 11am and the two ends of the plastic film should be opened at the same time. In the middle of the film, the ventilation film is cooled to prevent the high temperature from “burning the seedlingsâ€, and the film is kept warm at about 4 o'clock in the afternoon. In the case of low temperature and rainy weather, it takes about five days for the two films to be breathed and wet for about 2 hours to prevent the occurrence of cotton rot. Seedlings are planted with two leaves at the same time, and the mulching film is removed after 2-3 days. When picking up the film, it is best to choose sunny afternoon. After the irrigated water in the shack, the two sides or one side will be opened to prevent the death of the dead. After uncovering the film, cover the film in case of rain or extreme cold weather. To clear the ditch in time, adhere to dry education, and avoid watering the car. Clutch sunny days before and after the clover as soon as possible.
Steroids Powder name of steroids is adrenocorticosteroids. The adrenal glands of normal people secrete a certain amount of steroids every day to maintain normal physiological functions in the body, such as regulating the metabolism of blood sugar, protein, fat and electrolytes. It is an essential hormone to maintain life.
Steroid is widely distributed in the biological community of a large category of cyclopentane hydrophenanthrene derivatives, also known as steroids, steroids. Steroid compounds do not contain bound fatty acids and are non-saponifiable lipids; These compounds belong to isoprene like substances, which are formed by cyclization of triterpenes through intramolecular reorganization and chemical modification.
