Weiliangyou 86 12 is a combination of Huawei 338S and Huahui 86 12. The whole growth period of mid-season rice planting in the middle and lower reaches of the Yangtze River is 133.3 days, and the plant height is about 120cm. But the stem is stout, lodging resistance is good, tillering ability is strong, plant type is compact, and it can be planted closely.
The biggest highlight of Weiliangyou 86 12 is its high yield, which is nearly 8% higher than that of the control in the regional test. In recent two years, the output of many places has exceeded 2,000 Jin, which was paid in 202 1 100 mu super rice (dry grain), breaking the record of one-season rice output in Hunan.
Key techniques for high-yield cultivation of rice with a yield of 2000 kg per mu;
1, select the suitable sowing date.
One season of late rice was sown in the hilly area of Pinghu in the middle and late May, and one season of middle rice was sown in the mountainous area at the end of April.
2. Seed dosage of each planting method
Transplanting: 0.75 kg/mu, 6 inches *8 inches, 1-2 strong seedlings, tillering per tiller, seedling age is about 25 days.
Machine plug: 1.5 kg/mu, about 1.5 million mu.
Live broadcast: 1.5-2 kg/mu.
Step 3 apply fertilizer
Base fertilizer: 45% (15:15:15) compound fertilizer 35-40kg; Tillering fertilizer: urea10 kg; Prenatal fertilization: potassium chloride 10 kg (nitrogen application is strictly prohibited in the later period).
4, tube water
After transplanting, seedlings wither slightly, irrigate with dilute water to promote tillering, and dry seedlings in time. There is no water shortage from booting stage to heading stage, and there is water in the field 20 days after heading, and water is stopped 7- 10 days before harvesting. Don't dehydrate too early, so as not to affect the quality and increase the cadmium content of rice.
5, pest control
Soak seeds with prochloraz or strong chlorine to prevent seedling diseases. Control of rice planthopper and southern black-streaked dwarf in rice fields. Timely application of pesticides to control Chilo suppressalis, rice leaf roller, rice planthopper, sheath blight and false smut. Control false smut of rice 7- 10 days before heading, and apply pesticide at least twice.
6, timely harvest
Harvest 90% of rice in Huang Shi in time to ensure the excellent comprehensive quality of rice. You can choose to harvest after 2 pm. At this time, the water content of rice is low, so it is not suitable for sun exposure after harvesting, and high temperature and rapid drying should be avoided when drying. The water content should be controlled within 13.5%.
