Embodiment 1
[0017]Example 1 Comparison of the effect of rape aerial seeding time
[0018]From 2018 to 2019, a comparison experiment of the time of rape seeding was carried out at Wanzhang Lake Farm in Wuxue City, Hubei Province. The field experiment has 3 treatments, namely (1) T1, sowing one week before the rice harvest, (2) T2, sowing 3 days before the rice harvest, and (3) T3, sowing 3 days after the rice harvest.
[0019]Considering the operability of the field, the experiment adopts a large area non-repetitive test design, and the area of the large area is 200m2, Using sequential arrangement. According to the design of each treatment, rapeseed seeds were artificially sowed 7 days, 3 days before the rice harvest and 3 days after the rice harvest, respectively, using the method of simulated drone sowing. The sowing amount of each treatment was the same, which was 0.6 kg / mu. Except for the difference in sowing time, the field management of each treatment is the same. When the rice is harvested me...
Embodiment 2
[0023]Example 2 Comparison of rice straw returning methods
[0024]From 2018 to 2019, a field experiment was carried out on the effect of returning rice straw to the field on the emergence of direct seeding rape at Wanzhang Lake Farm in Wuxue City, Hubei Province. In the field experiment, three treatments were set up, namely (1) the treatment of not returning the rice straw to the field, the rice is harvested on the ground, and all the straw is removed and then planted; (2) the whole amount of straw is returned to the field treatment: the rice is harvested on the ground, After all the rice straws are pressed, the rapeseed is sowed and fertilized; (3) Straw mulching and returning to the field treatment: When the rice is harvested, a pile of 40cm is left, and the residual straw in the field is removed from the field. Lightly compact. Each treatment is repeated 3 times, completely random block arrangement, the block area is 20m2.
[0025]The method of artificial sowing is adopted, and the so...
Embodiment 3
[0028]Example 3 Comparison of spraying effect between improved rape leaf fertilizer and traditional leaf area
[0029]In 2017-2018, a comparative experiment was carried out in Guotan Village, Meichuan Town, Wuxue City, Hubei Province to improve the spray effect of rapeseed foliar fertilizer and traditional foliar fertilizer. There were 3 treatments in the field test, namely (1) control treatment, sprayed with clear water during flowering; (2) traditional foliar fertilizer treatment, sprayed with potassium dihydrogen phosphate and borax at the initial flowering stage, the concentrations of the two were 0.5% and 0.3 respectively. %; (3) Improve the treatment of foliar fertilizer. The main components of foliar fertilizer are potassium dihydrogen phosphate, calcium nitrate, magnesium sulfate and boric acid, and the nutrient concentrations are 0.2%, 0.5%, 0.3% and 0.1% respectively. When applied at the initial flowering stage, each treatment was sprayed with a manual sprayer according to th...
