How to Prune Pear Trees in Summer
Summer pruning, also known as pruning during growth, is mainly used to make up for lack of winter shear. Usually the following methods are used: (1) In addition to sprouting and thinning the buds less than 5 cm, known as de-emergence; thinning more than 5 cm of dense new shoots, known as thinning. Through de-emergence and thinning, nutrient consumption can be reduced, light conditions can be improved, selection can be improved and quality can be improved. In the process of raising seedlings of fruit trees, sprouts within 5 cm from the ground should be erased in time to ensure that the grafting site is smooth; the grafted seedlings should be eradicated with the following buds and shoots. (2) Picking up the appropriate period from June to July, removing the growing point of the year's shoot, known as picking the heart. Through topping, growth of shoots can be inhibited, germination of lateral shoots can be promoted, branches can be increased, accumulation of nutrients can be enhanced, flower bud differentiation can be promoted, and shoots can be overwintering. (3) ring circumcision that is ring peeling, stripping the skin of the twigs to prevent the downward transmission of organic nutrients, so that the branches above the excretory mouth accumulated more nutrients and promote flower bud differentiation. The annual circumcision time in Heilongjiang Province is in the middle and late June. The width of girdling is 1/3 to 1/5 of the diameter of the twigs. The skin peeled off can be affixed to the original place, or it can be put down. The former is called circumcision and the latter is called circumcision. (4) Twisted shoots For the growth of excessive, but it is not appropriate to remove the branches, you can use the twist tip method to inhibit its growth. The method is to hold the branches by hand, leaving a base, in the lignified part, rotate 180, sprain but not twist the branches, bent the branches from the sprain, not on other branches. Through the tip of the shoot, shoot growth can be inhibited and flowering can be promoted, and the base section can also be used to cultivate fruiting branches. Twist time coincides with girdling. (5) Take a branch to take a branch is used to shoot the root from the base to the top of a trip, damage the xylem but not broken, there is to ease the growth, differentiation of flower buds and promote short-stem effect. fresh frozen oil fish Oil Fish,Frozen Oil Fish,Fresh Oil Fish,Fresh Frozen Oil Fish Zhoushan Junwei Aquatic Products Co., Ltd. , https://www.junweiaquatic-intl.com
