1. Select seeds and plant them according to local conditions. The main choices for planting early rice fields in some areas of the city are Xiangfei No. 3, Anhui and Henan. It is more suitable to choose Ningbo Bridge and Yujiang Big Leaf for dry land and medium rice fields.
2. Do a good job of seed dressing and planting at the right time. There is a layer of wax on the surface of the seeds of Astragalus membranaceus, which is not easy to absorb water. Therefore, the seeds are slow to germinate. Before sowing, the seeds are added with about 30% of the chaff or river sand in the armpit for 10-20 minutes to increase the germination rate. At the same time, the rhizobium was inoculated, and 2 kg of superphosphate was mixed per kg of seeds for seed dressing. Seeding recommendations are based on the way the late rice is harvested. The mechanical harvesting is carried out in time after the machine is harvested. The field is required to be wet when sowing.
3. Do a good job in the "three ditch" package. After harvesting the double-season late rice, it is necessary to open new ditch in time, deepen the old ditch, and make the “three ditch†(main ditch, furrow, and ditch). Generally, every 2 meters or so, a trench is opened, and the depth of the ditch is about 0.2 meters. The main ditch and the surrounding ditch should be used to break the bottom of the plow, so that the ditch can communicate with each other.
4, apply good fertilizer. In the middle of December, 20-25 kg of calcium phosphate per acre was applied to fully exert the effect of increasing nitrogen by phosphorus.
5, promote early morning after spring. To achieve early Qing "three ditch." In the spring, there is a lot of rain. In order to create a good soil dry and wet condition for Ziyun Ying, it is necessary to clear the ditch and drain in the early spring to make the rain stop. At the same time, apply the grass fertilizer. After the spring, the growth rate of the milk vetch increased, and the need for nutrients increased. Therefore, it is necessary to look at the field, see the seedlings, and apply the quick-acting effect to promote the spring hair. Generally, apply 3-5kg of urea per mu to achieve the purpose of changing the small fertilizer for the big fertilizer and the inorganic fertilizer for the organic fertilizer.
6, timely prevention of pests and diseases. The diseases of Chinese milk vetch are mainly sclerotinia, powdery mildew, etc.; pests mainly include thrips, aphids, and leaf miners. The prediction of diseases and insect pests should be done in a timely manner, and the prevention and treatment should be carried out in a timely manner.
Hydraulic Diaphragm Metering Pump
Hydraulic Diaphragm Metering Pump/Hydraulic dosing pump, is characterized by the diaphragm reciprocating motion in the hydraulic work chamber, which means: the working chamber of the pump liquid end is caused from the diaphragm, but the diaphragm periodic motion is from the plunger reciprocating motion in the hydraulic work chamber, the accuracy of this dosing will be + 1%. The diaphragm is durable, and the component check valve ensure accurate ball control which in order to provide consistently accurate flow control through the pump, also it provide easy maintenance. The diaphragm technology provides high standard of safety, this eliminate the risk of leakage, then the pressure relief valve in the hydraulic end which to protect the overload problem. Under the different situation, hydraulic diaphragm metering pump can be joined together in efficient configurations. The hydraulic diaphragm metering pump usually used in chemical and petrochemical, pharmaceutical, cosmetic, food production and packaging industry.
