Artificially assisted pollination method for crisp pears

Abstract

The invention provides an artificially assisted pollination method for crisp pears and relates to the technical field of fruit production. The method comprises three steps: pollen collection, pollen baking and artificial pollination. In the pollen collection steps, varieties such as Chinese pears, spenceria ramalana, Cha pears, emerald pear, Yuanhuang pears and the like are adopted, flower buds are selected and collected in different times in a period from 1 to 2 days before the pollination tree blossoming to the first flower period, pollen sacs are peeled, impurities are screened, and pollen is conveyed to a pollen room to be baked; in the pollen baking step, the temperature of the pollen room for baking the pollen is controlled at 16 to 25 DEG C, the relative humidity is controlled at 60 to 70 percent, the disc loading is carried out in time after the pollen obtaining after the pollen drying, and the pollen is placed into a colored open bottle and is stored in a cold and dry position with the temperature being 2 to 8 DEG C and the relative humidity being 50 percent for use; and in the artificial pollination step, the pollination is started from the second day after the first flower and is stopped when the flower completely blossoms, and the optimum pollination in the whole day is from eight o'clock in the morning after dew is dried to six o'clock in the evening. The method has the advantages that the operation steps are simple, the pollen collection period is short, the pollen activity is high, the pollination probability is high, the natural condition limitation is small, and the orchard yield can be stably improved.

Description

Technical field: [0001] The invention relates to the technical field of fruit production, in particular to a method for artificially assisted pollination of pears. Background technique: [0002] my country is one of the birthplaces of the genus Pyrus. Most of the pears of the genus Pyrus in Asia originate in eastern Asia. Japan and Korea are also the original origins of Asian pears. [0003] Dangshan pear is a famous product among Chinese fruits. It is well-known at home and abroad for its huge fruit, bright yellow color, thin and juicy skin, multi-core meat and small, sweet and crisp. In 2010, Dangshan County was listed in the Guinness Book of World Records as the number one pear county in China. [0004] Crispy pears are cross-pollinated plants and must be cross-pollinated to bear fruit. Therefore, if there is no pollination tree or an orchard with unreasonable pollination trees, natural pollination will not work, and artificial pollination must be carried out to achiev...

Problems solved by technology

Most of the fruit trees are the most well-developed and most nutritious flowers that bloom first, and the fruit is round and large, but because it blooms the earliest, it is also the most likely to encounter bad weather, and it is most likely to miss the flowering period of pollinated varieties. Does not bear fruit, so hand pollination is required
