Study On The Technology Of No Tillage Direct Seeding Rape In Paddy Field

This research through the rice fields of rapeseed no-till live seeding time, seeding quantity, seeding method, seed treatment on plot test, the observation its growth looks, and analyzes its plot yield change, field demonstration at the same time, observing the planting benefit and practical value, in order to improve the reasonable Li County paddy rape plant planning, increase the planting area, improve the yield and quality, to provide the reference to increase farmers’ income. The main research results are as follows:(1) due to its ZhongWanDao is a season, after the rice harvest has occurrence peak in October, no-till live rape, sowing date can be early, can make full use of favorable conditions of TPS, deprivation make rape security good seedling emergence, promote vegetative growth. (2) appropriate seeding rate:live rape pendulum between each other individuals and groups, group base, weak, less population base, individual growth. The test results show that the amount of no-till live rape planting with 200-250 grams/mu advisable, density of 15000 plants/mu, but with the sowing date delaying, such as late after the middle of October, sowing quantity can be increased to 300 grams/mu, it is advisable to density of 20000 plants/mu.(3) appropriate seeding method and way of seed treatment:best lest tillage seeding planting mode, increase rate of 15%-22%.(4) Benefit is remarkable:the test results show that no-till live rape yield of 122.3 kg/ 667 m2, the output value of 538.12 yuan/667 m2 (according to rapeseed buy an average of 4.4 yuan/kg), and net income of 157.12 yuan, output and income than Li County live and ploughing plate field transplanting, the average production transplanting plate field less than 10.7 kg/667 m2, reduced 8%, the output value of 47.08 yuan less, net income is 227.62 yuan. Live than ploughing rape yield increased by 11.8 kg/667 m2, increase 10.7%, the value of RMB 51.92 high net income of 6.92 yuan.Comprehensive the above results, the paddy field rapeseed no-till live this technology not only simple, province, and high yield, high efficiency, can reduce the contradiction of labor tension, at the same time, practical strong, is the future direction of agricultural development and broad prospects.
