Method for adjusting flowering time of loquats

Abstract

The invention discloses a method for adjusting the flowering time of loquats. The method for adjusting the flowering time of loquat comprises the steps of: A. after fruit picking, appropriately removing over-dense branches of crowns of loquat trees planted in ecoregions of dry-hot valleys of the Jinsha River, and cutting the side shoots of dense branches with more than 2 shoots on the periphery of the crowns; shearing off cross and overlaid branches and weak branches; back cutting slim and fragile braches to a large extent, and back cutting strong bearing branches slightly; and back cutting the branches with young shoots at the connecting part of the old shoots and young shoots; B. heavily applying organic fertilizer within 5 to 7 days after shearing, and watering in time; and C. applying 25 to 40 kilograms of phosphatic fertilizer, 8 to 12 kilograms of potash fertilizer, 6 to 8 kilograms of nitrogenous fertilizer per 667 square meters of field from June to July, and spraying leaf fertilizer twice or three times in the period when the summer shoots and leaves turn green; and simultaneously, bending or cutting vertical branches, the diameter of which is larger than 1.5 centimeters, in a twisting way. The method for adjusting the flowering time of loquats can be used for delaying the flowering time of loquats planted in the ecoregions of dry-hot valleys of the Jinsha River, preventing the loquats from flowering in June or before June, and enabling the spikes to blossom in July to August concentratedly, the flowering ratio and fruiting rate to be high, the fruit quality to be high, and the fruit to be supplied on the market in a fruit off-season relatively concentratedly.

Description

technical field [0001] The invention relates to a method for regulating the flowering period of fruit trees. Background technique [0002] Loquat generally blooms in autumn and winter, and matures in spring and summer. Its flowering, flowering, and fruit growth and development periods are very different from the developmental timing of other fruit trees in spring flowers and autumn fruits. The ecological suitability of loquat varies greatly under different ecological climate conditions, so it has a great influence on the flowering period, the fruit setting rate of spikes and fruit quality. The flower bud differentiation of loquat belongs to the summer-autumn type, and temperature and fertilizer and water management play a decisive role in the flower bud differentiation of loquat; the growth of shoots and the morning and evening of stagnation period directly affect flower formation. [0003] In the dry-hot valley ecoregion of Jinsha River in Sichuan and Yunnan, the annual av...

Problems solved by technology

However, due to the early phenological period of loquat in this area, the long and scattered flowering period, and the prominent early flowering phenomenon are not conducive to the cultivation and management of loquat, and the early flowering period is often in the high temperature and dry season, the flowering time of loquat flowers is short, and the petals Difficult to open, less stigma mucus, unfavorable pollination and fertilization, low fruit setting rate, serious early fruit obstacle, and the formed fruit is short in growth and development period, small in quality, poor in quality, low in solid content, and has almost no commercial value. Consume the nutrition of the tree body, and seriously affect the economic income of fruit farmers
