High quality rice production technology

The quality of rice is affected by the characteristics of varieties, ecological environment and cultivation conditions. Only good seed and good methods can achieve high quality and high yield.
(1) Select the best natural ecological conditions. The production of high-quality rice in our province should be dominated by middle and late rice, and the early-season double-season rice production should be dominated by middle-quality rice. The soil and water requirements are not polluted. The content of soil organic matter is more than 2.0%, nutrients are abundant, balanced, and the soil is weakly acidic.
(2) Select species (combination) with high quality and high disease resistance to implement regional planting. Early rice is dominated by mid-range high-quality glutinous rice, such as Zaoxian 14, Jiayu 948, Zhouyou 903, Japonica 47 and Xieyou 9279, Xiangzaoxian 7 and Kyou 402. In the middle and single late rice, mainly middle-grade and high-quality glutinous rice and glutinous rice, such as Xieyou 63, Japonica rice 69 (91499), Japonica rice 51 (87641), Dangyu 3, Yangdao 6, Liangyoupeijiu and Zhongcan 898 and other indica varieties, Japonica 34 (80 You 121), Japonica 54 (88-93), Xiguang and Liuyou 121, Wuyujing 7, Wuyujing 4 and other indica varieties. The double-season late rice is dominated by high-quality, high-quality glutinous rice, such as Japonica rice 48 (70 Youhuang 9), Japonica rice 28 (B9038), Chuang 30 (88-23), late-night rice variety No. 2 and Xieyou 64 , Xie You late 3, etc.
(3) Adopting advanced breeding techniques such as dry nursery hoeing to cultivate a strong glutinous rice seedling. The arrangement of planting time should try to avoid the impact of high temperature and low temperature during the grouting period.
(4) Balanced fertilization. The fertilizing amount was 11-13 kg pure nitrogen, and the ratio of nitrogen:phosphorus:potassium was 1:0.5:0.8. The ratio of base, alfalfa and panicles is 5:3:2. The basal fertilizer is mainly composed of organic fertilizers, with nitrogen, phosphorus, potassium, and silicon, and is supplemented with appropriate trace elements such as molybdenum, sulfur, magnesium, zinc, manganese, etc., and attention is paid to the application of panicle fertilizers in later stages.
(5) Appropriately sparsely planted. It should not be dense in the appropriate density range. The number of acres in the middle of 1.5-1.8 million acres, double season early and late rice 2.0-2.5 million points. And the implementation of a wide line of narrow strains, the minimum planting, hybrid rice 1-2, conventional 3-4.
(6) Science irrigation. Take "Preserving the seedlings and sending old irrigation methods." That is to say, there is a combination of water and lutian in the early stage, and re-lighting at the late stage of the tillering stage. The water layer is kept in the field during the booting stage, water is intermittent during the grain filling period, and light water is applied in the middle stage, and water is sent to the old stage later.
(7) Integrated control of pests and weeds. Strengthen forecasting, early prevention. The use of biological pesticides in the later period, as little as possible to ensure the quality of rice health. Disable high residue pesticides.
(8) Appropriate release. With maturity of 85-90% is appropriate. Sun dry immediately after harvest. The use of bamboo mats and sun drying in the field of three-segment soil, as far as possible without cement floor drying.
