Scientific pollination improves apple fruit setting rate
Ready to work Choose flower-harvesting varieties and plants that have a strong affinity with the main planted varieties as flower-harvesting pollination varieties; the amount of flowers in the plant should be large, without affecting its own yield. The suitable time for collecting flowers is 2~3 days before pollination; collecting bell flowers or first blooming, mainly side flowers. The flowers collected from the anthers breathe vigorously and cannot be stacked. Take the pollen indoors in time, rub the two flowers against each other, and the anthers fall to remove the debris. Take the pollen and spread the pollen evenly on the paper, and bake it in a heated kang or a greenhouse at 20℃~30℃. After 1 to 2 days, the anthers will crack and the pollen will be taken out. Pollen storage: Put the inflorescences of fresh male flowers in a ventilated and dry room at 25℃ and spread them out on white paper, and let them dry until the pollen sacs split. Sift the scattered pollen to remove flowers, branches, leaves and other sundries. Then put it in a desiccator or a container with ash, or put it in a refrigerator or cold storage for later use. Pollen filler In order to reduce the cost of pollination, a certain amount of pollen filler must be added to the pollen before artificial pollination. Pollination method Artificial pollination. When the flowers in the center of the fruit tree bloom to more than 50%, point insemination can be carried out on the day the flowers bloom. Point insemination can be carried out with brushes, eraser pencils, cigarette filters, or with a pollination gun. It should be noted that when pollinating, the center flowers of the lateral and lower inflorescences should be spotted, and the top flowers of the short and medium branches should not be spotted too much on one branch. Wall bees pollinate the wall bees when the center flower is more than 50% open, and 400 to 500 bees per acre are used. Liquid pollination artificial pollination has a high fruit setting rate, but its work efficiency is slow. The use of liquid pollination can greatly improve work efficiency and has been widely used in recent years. It can be prepared with 5 kg of water, 15 g of urea, 15 g of borax, 250 g of sucrose, and 15-20 g of dried pollen. When more than half of the trees in the orchard have more than 60% of the center flowers open, it is the best time for the first liquid pollination. Can be sprayed once a day for three consecutive days, and can be used as needed Disclaimer: Some articles on this website are transferred from the Internet.

Suction blood vessel is also called vacuum collection blood vessel, according to the type of a total of nine categories. The details are as follows :1. Red head cover, no additives, used for the determination of some biochemical and immune indicators. 2. Yellow head cover, containing coagulant, can be used for biochemical and drug test determination. 3. Black cap, which is mainly used for the determination of erythrocyte sedimentation rate. 4. Light blue cap for the determination of coagulation factors. 5. Green cap for blood gas analysis and hematocrit measurement. 6. Light green head cover, liver function, blood lipid, blood sugar and so on were measured. 7. Grey cap, which is a special test tube for measuring blood sugar. 8. Purple head cover, mostly used for determination, blood type, blood routine, glycosylated hemoglobin and so on. 9 orange head cover, used for the determination of serum, hormones and so on.
