Since mid-October in the city, most of the districts and counties in the city have seen continuous rainy weather, with small to moderate amounts of rain, during the critical period when canola is planted, and even rainy weather has produced larger crop emergence, seedling growth, and transplanting. Affected by the fact that some seeded rapeseeds are severely seedlings, most transplanted rapeseed cannot be transplanted in the field due to the accumulation of water in the field or excessive soil moisture. In response to this situation, the national rapeseed industrial technology system Three Gorges Comprehensive Experimental Station specially prepared the "Rain-cured flood control emergency technical measures", the city's districts and counties shall be promptly conveyed to the farmers, strengthen the classification guidance, to minimize the adverse impact of this rainy weather on rapeseed production influences.

I. Emergency technical measures for flood prevention of rapeseed

1. Open “Three Ditches” in time, improve ditch system and raise ditch standards. In particular, it is necessary to deepen the gutters and gutters, and dig out the furrows outside the fields to reduce the width of the car. It is advisable to control the width of the car within 3 meters. (No-tillage can further reduce the width of the car, deepen the depth of the car ditch and the furrow), timely clear the waterlogging and ensure the smooth drainage, so that there is no clear water in the ditch, and the rain stops dry, and there is no dark stain in the plow layer.

2, to prevent rotten root dead seedlings. Too much rain will directly or indirectly cause rape rot dying, can take the following six prevention and control measures: (A) of the moisture content, the soil moisture under the wetland should be drained. Deep cultivator can be used to dig into the scales between the rows of rapeseed, promote the evaporation of water in the field, reduce soil moisture and eliminate toxic substances. (b) In case of damage caused by the occurrence of underground pests, top dressing may be combined with 40% dimethoate 20 ml per litter of defecation water. (3) For the occurrence of root rot and white rust, 1:7-10 white and black ash (ie, 1 kg of quicklime, 7-10 kg of ash) can be used for prevention and control. The method is: first loosen and then catch ash. Re-embedding manure water and soil protection seedlings. It is also possible to use thiophanate-methyl 100 g to spray 60-75 kg of water; or use carbendazim 100 g to spray 15-20 kg of water on seedling leaves. (4) Applying superphosphate or calcium magnesium phosphate fertilizer 20 kilograms, plant ash 15 kilograms, promote root development, and enhance pest resistance. (V) Diligently cultivating the soil to make the soil moist and breathable and promote the normal growth of rape seedlings.

3, due to the impact of continuous rain, the emergence of live rape is poor, should use a short time to stop the rain, and the time seedlings fill seedlings, to weak stay strong, to stay small to stay. For the live field where it is impossible and time for seedlings and seedlings to grow, and the growing trend is more prosperous, the mu can be sprayed with 15% paclobutrazol powder 30g watered 50kg once to avoid the formation of tall seedlings. (The use of paclobutrazol requires attention: paclobutrazol cannot be used when seedlings are not growing well.)

4, weed control. The use of herbicides in rainy conditions is often ineffective. At this time, it is necessary to clear the land for artificial cultivation and weeding. This will also improve soil permeability and reduce soil moisture.

Second, flood prevention emergency technical measures for transplanting rapeseed

1. Timely drain seedbed water, strengthen seedbed management, cultivate strong seedlings, and set seedlings in time, with 80-100 strains per square meter of seedlings. Due to the effect of continuous rain, rape that cannot be transplanted in time can be sprayed with 15% paclobutrazol 5g 5 kg water per seedbed to promote rape and prevent rape formation. A week before transplanting, Mu topdressing urea 3-5 kg, spraying pesticides, fungicides, so that with soil, with fertilizer, with medicine transplanted.

2. Due to the effect of continuous rain, most of the transplanted rapeseed could not be transplanted because of the waterlogging or soil moisture in the field. The first thing that these farmers need to do is to open up the “three channels” in a timely manner, improve the ditch system, and adopt methods and requirements that are the same as above.

3, should use the opportunity to stop the rain, timely transplanting. Promote the establishment of pendulums and fertilizers. The conventional method of planting holes was changed to open small ditch pendulums, and using finely divided loam soils to avoid rooting in the soil caused by planting holes, the waterlogging of the roots of the seedlings, and lack of oxygen and other undesirable phenomena, so that the survival rate of the seedlings An increase of 15-40% over colonization. The first seedlings were planted during transplanting, and the seedlings were individually transplanted after 4-5 days of transplanting. Transplanting rapeseed is required to be full, uniform, straight, and tight. That is, rape seedlings have less injuries, and the leaves and roots are complete. The size and size of the seedlings are planted, and the mixed plants are not to be planted; the seedlings are straight and rooted and the roots must be compacted. , transplanted side, do not plant every night seedlings. Deep planting of tall planting seedlings, in the case of seedlings and other fields, due to loss of time during transplanting, inevitably produce tall plantlets, transplanting should be used to carry out deep planting shovel, the high part of the deep buried in the soil, in order to facilitate antifreeze and seedlings and Reduce lodging.

4. Suitable for close planting, suitable density for transplanting rapeseed is 7000-8000 strains/mu.
