Variety selection. Autumn sowing vegetables in the early stage of high temperature and rain, late growth stage coincides with low temperature and drought. Therefore, carrots, radishes, Chinese cabbage, cowpeas, and cabbages should be selected for autumn sowing. They should be cultivars with wide adaptability, cold resistance, and high disease resistance.
Master the sowing time. The sowing date of autumn sowing vegetables should be strictly chosen so as to prevent the sowing date from being too early or too late. Before and after the summer heat began planting carrots; before and after the autumn planting winter water radish, cabbage. As soon as the seedlings are sowed, the phenomenon of falling flowers and falling leaves will occur. If the seed is sown too late, the yield will be too low. When sowing seeds are sown, they can be broadcast live between the summer and the autumn.
Pay attention to flood prevention. Seedlings of autumn sowing are prone to rainy weather, so the seedlings of autumn sowing vegetables should pay attention to drainage and flood prevention. The soil preparation can use sorghum or high ridge cultivation.
Timely prevention of pests and diseases. Autumn sowing vegetables are in the peak stage of occurrence of diamondback moth, cotton bollworm and brown spot. Insect pests can be treated with high-efficiency and low-toxicity pollution-free pesticides such as CPT, Green Vegetable Po, and High Chlorine Horse Spray. In case of disease, it can be controlled by agricultural streptomycin, alveolar oligo, and DuPont Kelu, etc. It is generally controlled once a day for 10 days, even for 2 or 3 times, and the drug is stopped 7 to 10 days before harvesting.
Flow cytometry is an important tool in cell biology research.10,000 cells per second, the cell size, DNA content, extracellular proteins can be quickly, large throughput statistical analysis, divided into With high analysis sensitivity, more than ten parameters can be analyzed at the same time. It is known as the "CT" of biological laboratory.
