Description

The trimming method of a kind of walnut treelet

Technical field:

The present invention relates to the technical field of planting fruit trees management, be specifically related to the trimming method of a kind of walnut treelet.

Background technology:

Walnut is deciduous tree, up to 3.5m, and bark canescence, shallow lobe, branch marrow sheet, the fine and soft hair of sprout tip tool, 2 years raw branch Chang Wumao.Long 25-the 50cm of winglike compound leaf, 5-9, leaflet, rare 13, ellipticity is avette to oval.Terminal leaflet is conventionally larger, long 5-15cm, and wide 3-6cm, the anxious point of tip or gradually point, base portion circle or wedge shape, be heart-shaped sometimes.Full edge or have not obvious cognate, surperficial bottle green, without hair, there is microtriche at the back side only arteries and veins armpit, the extremely short or nothing of petiolule.Long 5-the l0cm of male catkin, male flower has stamen 6-30, and calyx 3 splits; 1-3 consor of female flower, style 2 splits, crimson look.Fruit is spherical, diameter 5cm, celadon.Tool glandular hairs when children, when old, without hair, inner nut is spherical, yellowish-brown, there is irregular groove line on surface.The florescence 3-4 month, really 8-September of phase.18 kinds, be distributed in Europe, Asia, temperate zone, America to subtropics.5 kinds, China.Mostly be with material, oil plant and dry fruit tree variety.

There are many place plantation walnuts in China, and for the plantation of walnut, in pruning problem, always there are many differences, prune and defectively tend to cause leaf photosynthesis unreasonable, grow inharmonious, so just cannot guarantee the quality of walnut, and the growth of assurance walnut that cannot be good.

Summary of the invention:

Technical problem to be solved by this invention is that overcoming existing technological deficiency provides the trimming method of reasonable, simple to operate, the respond well a kind of walnut treelet of a kind of method.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A trimming method for walnut treelet, is characterized in that: comprise following methods,

Method one, the short branch of growing of cutting: a small amount of cutting back branch, promote a point branch growth, substantial inner, be specially the short head of cutting annotinous branch;

Method two, reduction branch behind: the sagging branch at the back that bounces back in time and monopodial growth branch, prevent from affecting the growth that extends branch on trunk branch and side shoot, be specially the small part on the perennial branch of reduction;

Method three, prune overstocked branch off: retain branch more, wipe out useless branch from base portion in time;

Method four, the in good time pinching of inner water sprout: the inner shoot growth of tree thorax is excessively prosperous, in the situation that space allows again, can develop into fruit bearing shoot and vegetative shoot, and concrete operations are for cutting off branch terminal bud;

Method five, remove most of male flower: in the time that male flower is too much, should extract in time most male flower, impel nutrition to carry to fruit;

The pruning at method six, the initial stage of bearing fruit: bear fruit in a large number during this period of time from bearing fruit, cut useless overstocked branch, water sprout, weak branch, to develop multistage skeleton branch and auxiliary support branch.Interior thorax will keep fruit bearing shoot and the vegetative shoot that density is suitable.

Beneficial effect of the present invention is: very simple, easy-to-understand of above-mentioned step, and very clear, be applicable to specialty or common staff's reference and use.And step very clear of setting forth, so also convenient operation.The inventive method is reasonable, simple to operate, respond well.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.
