Apple pollen pollination is a crucial link in apple cultivation, directly related to the yield and quality of apples. Apple pollen pollination is mainly divided into two methods: natural pollination and artificial pollination. Below, we will introduce these two pollination methods and their precautions.
I. Natural Pollination
Natural pollination mainly relies on wind and insects to spread pollen to the pistil stigma. To improve the efficiency of natural pollination, the following points need attention:
Select suitable varieties: In the apple orchard, choose varieties with similar flowering periods and strong pollen affinity to plant together for mutual pollination. Reasonable layout: Configure the pollination varieties and the main cultivation varieties in a certain proportion, such as a 1:4 or 1:5 ratio, to improve the pollination effect. Maintain ventilation and light in the orchard: Prune reasonably, remove dense branches and diseased and insect-infested branches, to allow the orchard to be ventilated and well-lit, which is conducive to wind pollination and insect pollination. Increase pollination insects: Plant some early-flowering plants in the orchard, such as oilseed rape and alfalfa, to attract insects to enter the orchard early and improve pollination efficiency.
II. Artificial Pollination
Artificial pollination is based on natural pollination and further improves the pollination effect through manual means, especially in cases where natural pollination is poor, artificial pollination becomes particularly important. The following are the steps and precautions for artificial pollination:
Collect pollen: When apple flowers first open, select healthy, disease-free apple trees, collect flowers, remove petals, and dry the anthers in a cool and well-ventilated place, then collect the pollen after the anthers split. Prepare pollen: Mix the collected pollen with fillers such as talcum powder in a certain proportion (such as 1:5) for easy spreading. Pollination time: Choose early morning or evening on sunny days, avoiding high temperatures, dryness, and windy weather. Pollination method: Tools such as brushes and powder sprayers can be used to evenly apply pollen to the pistil stigma. Number of pollinations: Generally, 2-3 pollinations are carried out, with an interval of 5-7 days each time.
Precautions:
Select high-quality pollen: The collected pollen should come from healthy, vigorous, and high-quality apple trees. Pollinate in time: Master the pollination time to ensure that the pistil stigma is mature and moist. Control the amount of pollination: Pollinate moderately, avoiding too much or too little to prevent affecting fruit quality. Avoid mixing varieties: During artificial pollination, avoid mixing different varieties to prevent affecting fruit quality. Strengthen post-pollination management: After pollination, strengthen orchard water and fertilizer management, promptly prevent and control diseases and pests, and improve fruit quality.
In summary, apple pollen pollination is a key link in improving apple yield and quality. Mastering the methods and precautions of natural and artificial pollination helps to improve pollination efficiency, thereby obtaining high-yield and high-quality apples. In actual production, the appropriate pollination method should be selected according to specific conditions to ensure the harvest of the apple orchard.
