The plum blossoms have a large amount of flowers, but the rate of self-cultivation is low. In order to obtain stable yields and high yields, flower and fruit management is an important part of it. Its flower and fruit management is mainly reflected in pollination, thinning and fruit thinning, and flower protection and fruit preservation. . First, pollination The optimum pollination time is at the beginning of flowering. Pollination should be selected within 3 days of flowering. Flowers pollinating more than 4 days will not pollinate properly. Flags suitable for pollination are stamen anthers which are partially unopened, pistil style is fresh, and stigma is mucus. Collect flower buds that have loose petals but not yet open to collect anthers and pollen, and configure the pollen solution to be sprayed with a sprayer for pollination. Pay attention to choosing windless weather and even spraying cloth. Second, Baohuabaoguo In production, growth regulators and nutrient elements are usually sprayed to promote the elongation of pollen tubes and promote fruit setting. Spraying 20 mg/L gibberellin during flowering, spraying 0.2% potassium dihydrogen phosphate at full flowering stage, 20 mg/kg of 2,4-D mixture, 0.2% potassium dihydrogen phosphate+2,4-D mixed solution during flowering stage 20 Milligrams/kg can increase plum production.
