Efficient Cultivation Technology of Potato and Rice Rotation
Through the research on efficient cultivation technology of potato and rice rotation,it was concluded that under local eco-logical conditions,the potato varieties Xisen No.6 and Xingjia No.2 were the best,and the rice varieties such as Rongqiyou 808,Tai-you 808 and Yixiangyou 2115 were the best.The best sowing time of potato is mid to late December,the harvest time is early to mid-dle of May,the best sowing time of rice is early to middle of April,and the harvest time is early to middle of September.The optimal planting density of potato was 5000～5500 plants/667 m2,and the optimal planting density of rice was 1.0×104～1.2×104 holes/667 m2.Under this technical condition,the yield of fresh potato is 2 500～3 000 kg/667 m2,and rice is 600～700 kg/667 m2.
