How many years does the loquat tree bear fruit without grafting

Loquat is a very common fruit, sour and sweet and delicious, usually ripe in early summer. Most of the loquat trees planted on the market are grafted, so how many years do not grafted loquat trees bear fruit?

First, how many years does the loquat tree bear fruit without grafting?

It usually takes 3-5 years for loquat trees to bear fruit without grafting. If the loquat trees sown do not bear fruit, it may be the problem of variety and soil, and the seedlings have atavistic phenomenon, so it is difficult to blossom and bear fruit normally in areas other than the place of origin, so high quality varieties need to be grafted for improvement.

Second, the growth environment of loquat trees.

Loquat like light, slightly tolerant to shade, like warm climate and humid soil with good drainage, slightly resistant to cold, not tolerant to severe cold, slow growth, average temperature above 12: 15, winter not lower than-5 ℃, flowering period, young fruit stage no less than 0 ℃, can grow well.

In general, Henan Province can also be cultivated, but when the fruiting period is less than 2 degrees below zero, the young fruit will be frozen, and the suitable area for cultivation is in the middle and lower reaches of the Yangtze River and the south. It had better be fertile soil.

3. Cultivation methods

The main results are as follows: 1. Ring cutting, pulling branches and slightly broken branches promote flower bud differentiation control. In late June, cut 2-3 times on the trunk and smeared the wound with 50% tophan wettable powder 50 times to prevent bacterial infection; from June to July, all the main and side branches above lcm in diameter and 70cm in length were pulled into an angle of 50 to 55 with the trunk, and the branches were drawn to develop horizontally, so that the branches grew inclined and drooped slightly; other branches were twisted and rubbed to change the growth direction of branches to facilitate the formation of flower buds.

2. fertilizer and water promote the control of flower bud differentiation.

From June to August, without nitrogen fertilizer, properly increase phosphorus and potassium fertilizer; from June to August to before flower bud formation, if the growth of vigorous branches could not be controlled, the mixture of 600 and 800 times of potassium dihydrogen phosphate and boric acid could be sprayed on the leaf surface for 3 times. From June to September, for the vigorous growth of loquat trees, it is necessary to open ditches to drain Rain Water, reduce soil moisture, properly truncate part of the root groups of topsoil and reduce branch moisture.

3. Promoting and controlling flower bud differentiation with regulators.

Using paclobutrazol (PP333) soil, 0.5g 000mg/L was sprayed on leaves once on June 20 and 30, or paclobutrazol 1000mg/L was sprayed on each leaf once a month from June to August, so that the growth of summer shoots stopped quickly, increased the concentration of cell sap and Cmax N, and promoted.

Loquat flower bud formation.
