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.

The invention relates to a simple method for promoting AP sweetsop flower formation. The simple method for promoting the AP sweetsop flower formation specifically comprises the steps of performing selection, clipping, flower formation promotion, water management and fertilizer application management in a clipping and flower formation promotion period, wherein the clipping and flower formation promotion period ordinarily ranges from the last ten-day period of August of the current year to the first ten-day period of March of the next year; selecting and topping young sprouts grown in the current year, spraying plant growth regulator mixed liquor on topped branches without half of leaves and then performing the spaying for one time every three days, totally performing the spraying for 3-5 time so as to promote axillary bud growth, and providing guarantee for flower bud differentiation.
