Autumn sowing
“Regenerating rice is a rice cultivation mode that saves labor, saves money, and increases grain yield. It is particularly suitable for us to promote planting in hilly and mountainous regions. We have mastered 'scientific fertilizer topdressing, low-level disease prevention and control, germination and retention of piles, and early tube regeneration in field management. "These quarters are key technologies to ensure the stable production of 200 pounds of paddy rice and 400 pounds or more of high yield." Recently, the author visited Anfu Village, Cotton Po Town, Naxi District, Ganzhou City. I saw the lush rice growing in the paddy field growing gratifyingly in the field. Su Jizhong, a technician at the Agricultural Technology Promotion Service Center of the town of Pao, which guides the villagers to scientifically manage ratoon rice, told the author.
Root fertilization
The regeneration rice requires large amount of fertilizer. After the harvest of the first season rice, the weeds should be promptly removed, the piles should be set up, and 7-10 kg of urea should be applied per acre to promote early-onset and fast-growing seedlings.
From the break to the heading stage, roots were used for fertilization. Each acre had 1 gram of 9O2, 0.25 gram of white rice vinegar, 0.1 kg of potassium dihydrogen phosphate and 50 kilograms of water. When the heading reaches 1/3, use 0.5-1.0 g of “9-2000†and add 0.2 kg of urea to spray water to ensure the nutrient requirements in the later period of the ratooning rice, promote the heading, improve the seed setting rate, and increase the grain size. Number and grain weight increase production.
Pest control
In the control of pests and diseases, two diseases and diseases are mainly used to cure other diseases and pests.
Erhuai, attending a generation, picking the second generation, Qiaozhi three generations. When the rate of dry shoots in the field reaches 5%, it will be treated with pesticides. In addition, 48% of Lohsien EC will be sprayed with 100 ml of water and 50-60 kg of water will be sprayed. Rice planthoppers have 15 or more worms per locust, which is controlled by the medicine. The mulberry is sprayed with 25% buprofezin 50g plus 50-60kg of water. Roll leafhoppers, 500 moths per acre or 20 insecticides per 100 insecticides are used for prevention and treatment, and 48% Loess Herbal Oil is added to 100 ml of water and 60 kg of water to spray. When the borer borer, rice planthopper, and rice leafroller occur simultaneously, the plant can be used with 48% Loessben EC 100 ml plus 10% imidacloprid wettable powder 40 g plus water 50-60 kg evenly sprayed.
Rhizoctonia is a sporadic disease, mainly prevention, in the delivery period, the booting phase, breakage of each medication 1 times, mu 30% Ai You EC 150 ml or 5% Jinggangmycin 250 ml plus water 50 - 60 kg spray.
Rice blast, used in the early stage of disease and drug control during the break period, with 100 grams of kilograms of emulsifiable concentrate or 20% of tricyclazole WP and 50 ml of water spray.
Germination
Axillary buds in the 2-6th node of the first season rice can germinate into the panicle, and the axillary buds in the inverted 2 and 3 positions have the highest germination rate, which constitute 70%-80% of the number of panicles. Therefore, the first season rice must master the harvest period and stay. The height of the pile, the first season rice to grasp timely harvest. Too early or too late is not conducive to budding growth and shootout. Retaining pile height of about 40-50 cm, retain the inverted 2 buds, mu effective ear to reach 250-300,000 spikes, leaving high piles can retain more storage material of rice piles, meet the nutrient requirements of renewable alfalfa, and promote regeneration. Germination and growth.
Early tube regeneration season
First reapply bud shoots and buds. 15-20 days after the head rice is full, 20 kg of urea per acre is used as bud seedling fertilizer. After the first season rice was cut 1 to 2 days, 5 kg of urea was applied and 5 kg of potassium fertilizer was used to promote budding fertilizer. In the heading stage, foliar fertilizer was sprayed with 2 grams of "920" plus 0.2 kg of potassium dihydrogen phosphate plus 60 kg of water to promote grouting, increase the seed-setting rate and 1000-grain weight, and increase the yield.
Followed by intermittent irrigation, 5 to 7 days after cutting, the field is kept moist, shallow irrigation after irrigation, alternating wet and dry, not to prematurely cut off water.
Finally, we must pay attention to the control of sheath blight, ear strength, rice planthoppers and leafhoppers. As long as the prevention and control are in place, it can achieve 100-200 kg of renewable rice per mu.
