The development of high-quality rice is a major trend in rice production today and after. Planting high-quality rice can increase the price of grain by 15-20%, and increase the per-mu production value by 80 yuan.
1. High-quality rice combination: Guang 8 You 673, Zhongzhe You 8 and Zhongzhe You 10
2, the main cultivation techniques: According to the requirements of high-quality rice production, promote high-quality and high-yield cultivation techniques.
1 Cultivate strong broth: Wet seedlings are used, and the amount of mu is 2 pounds. Before the seedlings are planted and rooted, keep the surface moist and ventilated; after rooting the seedlings, take shallow water ground irrigation to achieve water temperature regulation, fertilizer regulation, and promote pupa; spraying 15% paclobutrazol 500 times solution in the late season. (1 g of 15% paclobutrazol plus 1 kg of water), nurturing strong clams.
2 close planting specifications: 1.6 to 1.8 million acres inserted acres, basic seedlings 6 to 80,000.
3 Fertilization technology: Advocate organic and inorganic combinations, combined application of nitrogen, phosphorus and potassium. Generally, organic fertilizer accounts for more than 30% of the total amount of fertilizer, and the ratio of nitrogen, phosphorus and potassium is 1:0.4:0.8. The goal is to produce 1,000 pounds of rice per mu, and apply 20 pounds to 22 pounds of pure nitrogen per acre, 8 pounds of phosphorus pentoxide and 18 pounds of potassium oxide.
4 Fertilization methods: Master the principles of “pre-promoting, middle-control, and post-supply†fertilization. The amount of early-stage fertilization should be stable, and the amount of later-stage fertilization should be appropriate, and dynamic regulation should be carried out according to the population quality and long-term growth. Mushi 1000 kg to 1500 kg organic fertilizer as base fertilizer; Phosphorus fertilizer as base fertilizer applied one time; Potassium fertilizer base fertilizer and panicle fertilizer twice, each accounting for 50%; Nitrogen fertilizer sub-basal fertilizer, barley fertilizer, panicle fertilizer and grain fertilizer 4 times, the ratio is 4:3:2:1; spike fertilizer application of 98% magnesium sulfate 5 kg, 20% zinc sulfate 1 kg and other trace elements, to ensure the balance between the various elements and trace elements.
5 outside the dressing: the heading period combined with broken mouth medicine with 0.2 to 0.3 kg of potassium dihydrogen phosphate to 120 kg of water spray. The yellow color of the leaves is obviously yellow, and 1 to 1.5 kg of urea can be sprayed.
6 Reasonable irrigation: Keep the shallow water layer in the returning green period, promote the flooding by shallow water during the tillering period, and effectively dry the field at the end of the tillering period. The degree of the drying field is generally lightly roasted until lightly roasted for 5-7 days. Muddy fields should be re-roasted to control ineffective delivery and promote root growth and strong stalk cultivation. Booting, heading, and flowering stages all maintained a shallow layer of water. Intermittent irrigation was performed after heading to maintain dry, wet and dry conditions. It was advisable to cut water 5 to 7 days before harvest.
7 Diseases, Insects and Weeds Prevention and Control: Strengthen the prediction and forecast of diseases, pests and rats, use pesticides rationally, and use low-toxic, low-residue, high-efficiency and safe pesticides.
8 harvest sun Valley: in the rice maturity reached 90% to 95% timely harvest. Sun Valley is evenly diligent to turn over the sun, drying to about 14% moisture.
