With the arrival of winter, the occurrence of freezing disasters has occurred, and the anti-freeze and cold-resistant work is done to keep the crops safe for winter, laying a solid foundation for the next year's high yield.
1. Select crop varieties suitable for low-temperature cultivation in winter, use greenhouse insulation cultivation, seedlings, cover the crops with double-layer film-covered straw, and strengthen the cold and anti-freeze; on the other hand, apply heat-increasing organic fertilizer and spray new high-fat film leaves. Fertilizer, improve the plant's resistance to stress, promote the effect of heat preservation, and do a good job in clearing the ditch of the field crops, eliminating the accumulation of water, and reducing the occurrence of crop damage and freezing damage.
2. Do a good job in antifreeze and warmth. Greenhouse vegetables, strawberries, flowers cultivation, pay special attention to the cold and anti-freeze work, timely spraying the tree guards general insulation and antifreeze; the film should be tightly sealed, pay attention to prevent the wind from being scratched, can be covered with straw at night, etc.; It can build a small shed in the shed and double-layer insulation protection. Coastal areas should also guard against the danger of northerly winds.
   3. Strengthen field management of winter crops. It is necessary to grasp the fine weather and do a good job of clearing the ditch, checking the seedlings and filling the shortage of rapeseed, barley and winter vegetables. If it has not been trenched, it is necessary to open the ditch and channel in time, and the ditch and channel are matched to ensure that the rain stops and the water is drained, and the accumulated water in the field is removed in time to avoid the hazard of wetness. At the same time, it is necessary to look at the fertilization of the seedlings, make full use of the light and heat conditions before the winter, cultivate strong seedlings, and ensure that enough acres of seedlings are reached before the year.
   4. Tea, mulberry, orchard should do a good job in early winter management. Attention should be paid to cutting off pests and diseases, weeding, winter ploughing, fertilizing, covering the soil, spraying the generals to protect the trees, doing a good job in clearing the garden, and laying grass on the ground in the yard to facilitate the fight against freezing damage.
Lab pump operates by pumping fluids through the Peristaltic Pump tube squeezed rotating rollers in the pump head that squeeze the liquid out of the tube with compression force.
The lab pump is a liquid delivery device that can control the flow rate. It has the characteristics of high delivery accuracy, strong corrosion-resistance, small shearing effect, simple operation, easy maintenance, and can effectively avoid cross-contamination. It has a very wide range of laboratories. Applications. From cell culture to in vitro organ research, from material preparation to water treatment technology optimization, from food ingredient extraction to food preparation technology improvement, lab pump may be used as power to achieve accurate fluid transmission and processing operations during the experiment.
The mechanism of this lab pump's action which only delivers the liquid by the tube allows fluids to be dispensed without introducing contamination. This makes them ideal for dispensing liquids in both biological and chemical labs.Lab Pump,Digital Lab Pump,Transfer Peristaltic Pump,Lab Scale Peristaltic Pump
