Hickory branch tip culture method suitable for Southern regions

Abstract

The invention discloses a hickory branch tip culture method suitable for Southern regions. The method includes following steps: (1), thinning or retracting upright big branches and crossed branches: before hickory germination in winter, cutting or retracting the upright big branches and the crossed branches of hickory to enable a hickory tree to be integrally ventilated and light-pervious; (2), lopping for the first time: before hickory germination in winter, lopping one-year-old long branches by 1 / 3-1 / 2 of total length, and cutting off the tail ends of branch tips; (3), lopping for the secondtime: from April to May in spring, lopping medium-long branches of the current year by 1 / 3 of total length, and cutting off the tail ends of branch tips; (4), lopping for the third time: from May toJune, lopping medium-long branches of the current year by 1 / 3 of total length, and cutting off the tail ends of branch tips. The method is suitable for hickory branch tip culture in Southern regions,the number of branches, especially medium-short branches can be increased, relative balance between nutritional growth and reproductive growth of hickory is realized, flowering, fruit bearing and early fruiting of hickory are promoted, and yield and quality are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a hickory branch tip cultivation method suitable for southern regions. Background technique [0002] Hickory is one of the famous dried fruit tree species and woody oil crops. Its nuts are large, thin in shell, high in kernel yield, delicious in color and rich in nutrition. It can be used as an ideal nutritious food or processed into various candies pastry. Under the condition of natural growth, the vegetative growth of hickory in the southern area is vigorous, the branch angle is small, all kinds of branches are easy to be bare and out of joint, the inside of the canopy is empty, the fruiting parts are few, the quality of flower bud differentiation is not good, late fruiting, serious flower and fruit drop and yield It is relatively low, which seriously restricts the healthy and rapid development of the pecan industry in the south. The short branches (about 5-3...

Problems solved by technology

Under the condition of natural growth, the vegetative growth of hickory in the southern area is vigorous, the branch angle is small, all kinds of branches are easy to be bare and out of joint, the crown is empty, the fruiting part is few, the quality of flower bud differentiation is not good, late fruiting, severe flower and fruit drop and high yield Lower level, which seriously restricts the healthy and rapid development of the pecan industry in the south

The short branches (about 5-35 cm in length) of hickory are the main body of the fruit, and a sufficient number of short branches is an important basis for the high and stable yield of hickory. However, many annual shoots of hickory trees in the southern region grow to 1-2 meters , few branches, stop growing later, suitable for cultivating and expanding the crown and not easy to form flower buds; when the hickory tree is large, the vigorous growth of the branches will easily lead to the airtightness of the crown and affect the ventilation and light transmission, aggravating the damage of diseases and insect pests and not conducive to flowering result
