A sapling tree shaping is to cultivate good skeleton, laying the foundation for the rapid expansion of the crown, prompting early results, early yield. Walnut tree is generally sparse layer dispersed form two kinds of shapes and natural happy. (1) sparse layer dispersed form: central leader tree is more obvious, the main branch 5-7, 2-3 layers, so that more than tree branches, canopy, high yield, plastic focusing stem height of 1.5-2.5 meters, poor soil conditions, leaving dry must be low, the main branch of the position and orientation of students to be configured properly. The distance between the main branch of 1-1.5 meters, not too close, the first of three main branches of the collateral base about 1.5 meters away from the trunk, too close to the door side of the form, the more the distance between the crown periphery of each of the more collateral should be reduced. To keep the growth advantage of central leadership branches. Under normal circumstances, you can not easily change the head, which is different from other fruit tree pruning important features. (2) natural happy shape: central leadership Dry obvious ,2-3 main branch, 2 or 3-prong fork structure, in order to accelerate the expansion of walnut sapling crown, increasing the number of branches to achieve results and early yield, can be used in summer scissors and cut method autumn to promote more lateral buds sprouted new branches. Xiajian growth coming to an end when the snags, 50 cm above the top of the development branch cut 2-3 buds to promote lateral bud sprouting and shoots full, increase the number of branching in the coming year, autumn leaves before cutting is carried out, Shear sticks outside the top developmental extension or branch is not fulfilling part of the long one-third to one-quarter, full notches on the upper outer full buds, so the crown of the year to expand and draw more students development branch . For over a year old, thin dense branches can be properly cut. Walnut trunk strong, apical dominance is particularly pronounced bud, bud bud development than full mast, canopy significantly, according to this feature, the use of sparse layer-shaped trunk is appropriate. Its shaping method: dry high 80cm ~ 150cm (if the year is not high enough seedlings, seedlings can be grown year after plastic surgery). Planting year without any pruning, only the trunk up, please, and protect the terminal bud (terminal bud damage if, instead of an optional one strong bud), until the spring sprout buds up upright growth, which was dry as a center bud 5 to 6 buds lower part of the collateral will germinate, 5 to June election distribution prosperous growth of 3 to 4 main branch collateral for the first layer, the remaining shoots all erased. 2 by the same method of cultivation of the main branch of the second layer, the second layer 2 to 3 Reserved main branch (the first layer a distance 80 ~ 100cm), a third layer selected from the first three years of the main branch, Reserved 1 ~ 2 main branch, and the second layer distance 60 ~ 80cm. 1-4 years do not trim the main branch, naturally meristem collateral, expanding canopy. Usually 3 to 4 years forming, molding tree height of about 3 ~ 5m. 2 Results walnut tree pruning Jieguomuzhi buds are mixed buds, generally not every cut, cut only a thin dense branches, twigs, worms branches, overlapping branches, so that air and light, the full realization of robust growth-promoting Jieguomuzhi and development branch. (1) Jieguomuzhi pruning: 1 Year crown peripheral branches robust growth is often Jieguomuzhi next year, generally not short cut, but Jieguomuzhi too much can cause crown canopy, the impact of air and light, to be appropriate Jieguomuzhi sparse to the thin part to stabilize production and promote normal development of the tree. (2) extend the pruning branches: for 15-30 year old full fruit tree top canopy perimeter of each group bough pumping raw 1-year extension of branches, may be cutting back, like buds at the top 2-3 in the bud branches are not full, plump buds may be to cut back in place to expand the canopy and increase the results of the site. (3) pruning leggy branches: leggy branches mostly hidden by the branches bore backbone buds form, more vigorous growth occurs in adult trees and aging trees, cut off from the base of the last multi-called "clean bore" . In recent years begun to use the results of leggy branches. According to experience, Hebei, Shandong and other provinces, leggy branches bore part of emptiness, Ke Yi position and growing strength of the students in half to one third of the buds of the stub, 2-3 years after the cut The results can be formed branches, additions gap, expanding the scope of the results, the purpose of the three-dimensional results. (4) drooping branches pruning: The bifurcation of retraction, and cut off the dry pest branches, drooping branches too close to gradually cut down. The result of walnut crown continues to expand, increasing the results of the site, prone and contradictions growth results, ensure walnut achieve high and stable yield is the main task of this period trim. Therefore, the pruning should always pay attention to cultivate good Zhizu, make good use of auxiliary support branch and leggy branches, sticks and timely processing behind the drooping branches. Preliminary results from the beginning, should plan to develop robust results Zhizu, increasing results site. Prevent crown bore emptiness and results relocation site. After entering the flourishing should be strengthened Zhizu training and rejuvenation. Zhizu culture can be "first zoom" and "go back branches, twigs left oblique" pruning methods. Leggy branches generally do not stay in the early results, in order to avoid disrupting the tree in full fruit can be cultured as Zhizu controlled chaos in a timely manner to the branches, so as not to affect the backbone branches and Jieguomuzhi. Many do not enrich the drooping branches, the result is poor, only the consumption of nutrients, should be dealt with under the specific circumstances. Cloud new walnut seedlings grafted seedlings, Japan fragrance, Shu new series of shell walnut varieties cultivated in our best batch of Thanksgiving back to the community, the company has 1,200 acres of walnut hanging orchards, 500 acres of grafted seedling cultivation base, in this solemn promise: spot lifter, lifter can supervise, does not sell any redeployment of seedlings, the accumulation of seedlings, Paul survived, then see the flower planting fruit, fake a compensable 10, to visit send you try to grow seedlings. ============================================== Company Address: Sichuan Province, Mianyang cents scenic sea Contact: Mr. Zhang Tel: 15284021004 Contact QQ: 273394138 Website: http://www.scllf.com http://91199.site.booen.com http://www.hetaomiaojd . icoc.cc http://hetaomiaojd.co.bokee.net http://user.qzone.qq.com/273394138
