First, prepare for the selection of pure quality late-maturing varieties, new varieties of the year, high germination rate, high yield per mu; half-day drying before sowing; then add the same amount of river sand, put it into the woven bag and rub it hard, scratching The seed coat removes the wax and can increase the germination rate by 30%. After soaking for 24 hours, the seeds can be sown by the buds.
Second, the new mixed area of ​​mixed seed and fertilizer must be mixed with rhizobium, which is the key measure for the success of planting Ziyunying in the new area. The old mixed bacteria can also significantly increase the yield. The seed dressing fertilizer can be mixed with 5 kg of superphosphate plus 30 kg of ash and 50-100 kg of decomposed farmyard manure for 7 days, then mix the seeds with the mixture.
Third, the sowing time is carried out after the late rice stalk hook head, the acre of Ziyunying 1-1. 5 kg mixed radish green 0•25 kg; the Chinese daisy, radish green and late rice symbiosis 15-20 days is appropriate; sowing When the field is kept moist, excessive moisture or drought is not conducive to its growth.
Fourth, water management Ziyun Yingxi moist, not only drought, but also afraid of water. The whole growth period should ensure that the soil has a certain humidity, so that the field can be irrigated; after harvesting, the cross ditch and the ring-shaped ditch should be opened, the ditch and the ditch should be connected, the heavy rain will not accumulate water, and the rain will pass through the field; in case of drought, When the soil is whitish, the soil should be irrigated in a timely manner to adapt to the growth requirements of the milk vetch.
5. Appropriate topdressing of fertilization, especially for paddy fields with poor fertility, should be applied 1-2 times of fertilizer, with “small fertilizer and large fertilizerâ€, which can significantly increase green manure yield. Fertilization is divided into three stages: base fertilizer, winter fertilizer and spring fertilizer.
Sixth, pests and diseases control diseases have sclerotia and powdery mildew, insects are aphids, thrips, leaf miner, pea pods, Spodoptera litura, etc., should pay attention to comprehensive prevention and treatment.
PVC Waterproofing Membrane is an advanced-formula, heat-weldable PVC thermoplastic membrane that is designed for long-term weather-ability and performance. The physical properties of the membrane are enhanced by a tenacious, weft-inserted polyester fabric that is encapsulated by thick PVC- based top and bottom plies.
The smooth surface of the PVC membrane allows for a total-surface fusion and permanent weld, creating a consistent, watertight, monolithic roof assembly. PVC can be used in adhered and mechanically fastened systems.
