Cultivation method for fruiting by using loquat strong branches

Abstract

The invention provides a cultivation method for fruiting by using loquat strong branches. The cultivation method comprises the steps of loquat treetop promotion, treetop control and flower promotion. The method particularly comprises the following steps: 30-40 days before fruit picking, applying 0.5-2.5kg of compound fertilizer to each plant; after fruit picking, carrying out cutting treatment on the fruiting branches by leaving 5-10cm of treetops, leaving 1-3 newly germinated treetops while removing all the rest treetops, and cultivating until the branches, of which the thickness is 0.9-1.5cm, the length is 20-60cm and the number of leaves is 10-20, result; after transferring into the stage of flower bud differentiation, spraying 0.4-0.5 wt% KH2PO4 until the leaves are moist, shallowly turning up the soil by 4-6cm in combination with the tree disks, and controlling the relative water content of the soil at 40-50%, thereby carrying out treetop control and flower promotion while no fertilizer is applied; and avoiding flower thinning in the heading stage and blooming stage, and leaving 4-8 fruits / spike in the young fruit stage. The method can lower the labor cost, increases the loquat yield, and enhances the loquat planting benefit.

Description

【Technical field】 [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a cultivation method utilizing loquat long and strong branches to bear fruit. 【Background technique】 [0002] Loquat is a fruit tree that blooms and bears fruit at the top of the branch tip. The proportion of fruiting branches and the number of fruits in ears are the main factors affecting its yield. In traditional production, because the long and strong branches of loquat grow too vigorously and the heading rate of branch tips is low, therefore, in the existing loquat production, most of them are cultivated with medium growth (thickness 0.6-1.0cm, length <30cm, number of leaves <15 pieces). Branches bear fruit to increase the earing rate of branches; artificial flower thinning and fruit thinning measures are adopted during the flowering and young fruit stages to control the proportion of fruiting branches and the number of fruits left in ears, ...

Problems solved by technology

In traditional production, because the long and strong branches of loquat grow too vigorously and the heading rate of branch tips is low, therefore, in the existing loquat production, most of them are cultivated with medium growth (thickness 0.6-1.0cm, length <30cm, number of leaves <15 pieces). Branches bear fruit to increase the earing rate of branches; artificial flower thinning and fruit thinning measures are adopted during the flowering and young fruit stages to control the proportion of fruiting branches and the number of fruits left in ears, and the amount of fruit remaining accounts for 60% to 70% of the total number of branches. The amount of fruit per spike is about 3 to achieve the purpose of cultivating large fruit. However, due to the excessive number of spikes, the proportion of labor cost expenditure for management operations such as flower thinning, fruit thinning, fruit picking, bagging, and picking is too high, and the yield decreases.
