In recent years, due to the erratic weather and climate change, the increase of severe weather and irregularity can lead to an increase in the risk factors of double-season rice cultivation. It is the key to scientifically and reasonably match early and late rice varieties. Variety match 1. The principle of maturity matching. According to geographical and climatic conditions, the contradiction of planting double-season rice season is more prominent, and there is not much selectivity in early and late rice varieties. The pattern suitable for early and late rice varieties is only early-maturing early rice varieties with mid-maturing late-late rice varieties (105 days cooked) With the 120-day maturity period, the mid-maturing early rice varieties with the mid-maturing late rice varieties (110 days maturity with 115 days maturity) can ensure stable and high yield in both early and late rice planting. 2. Quality matching principle. In order to highlight the goal of green, high-yield and high-efficiency, the area planted with double-season rice is to implement the “early super late†planting mode, namely, early rice planting super rice and late rice planting high quality rice. Variety selection Screening for varieties suitable for planting early and late rice for rational combination is the basis for stable yield and high yield of double-season rice planting. After years of introduction and demonstration, suitable early rice varieties are: Xiangzao No. 6 (87 early), early morning 39. Wen 814, Xiang Zaoyu No. 45, Xiangzao No. 32, Zhongjia Zao 17, Tan Liangyou 83, Tan Liangyou 143, etc.; late rice varieties include Taoyouxiangzhan, Xiangyueyu 13 and Yueyou 9113 , Tianyou Huazhan, Yueyou 518, etc. Sowing time According to climatic conditions, suitable for rice in late March, depending on weather conditions seeding (using dry nursery nurse coated seeds can be sown about 7 days in advance); Xiangwanxian 13 late ripening varieties on June 8 to 10 days sowing; peach Yuka accounted maturity varieties to planting 15 to 18 June, 518 Yueyou maturity varieties planted around June 20.
