Abstract

Provided is a method for transforming an aged mulberry field by cutting trunks. The method for transforming the aged mulberry field by cutting the trunks comprises a double-trunk cultivating method and a single-trunk cultivating method. According to the double-trunk cultivating method, after the trunk of a mulberry tree is cut off, when shoots grow out of the connection position of the root collar of the mulberry tree, bud thinning is carried out, a stem is maintained, and pinching is carried out and branches are maintained to form a first branch trunk, when the branch grows to 40cm to 50cm, pinching is carried out and buds are maintained to form a second branch trunk, and winter clip is carried out at the position of 1.2m away from the ground. In the second year, clip and cutting are carried out after spring silkworms are bred, buds are used as branches for producing mulberry leaves after growing out, and winter clip is carried out at the position 1.3m to 1.5m away from the ground after silkworm breeding is finished. According to the single-trunk cultivating method, after the trunk of a mulberry tree is cut off, when shoots grow out of the connection position of the root collar of the mulberry tree, bud thinning is carried out, a stem is maintained, and pinching is carried out and branches are maintained to form a first branch trunk, pinching is carried out and branches are maintained at the position 40cm to 50cm away from the ground, and when a second branch trunk grows to 70cm to 80cm, pinching is carried out and branches are maintained for a third time. The method of cutting of the trunks to transform the aged mulberry field shortens a field construction period, improves production, saves field construction cost, increases economic benefit, and can achieve the effect of a new mulberry field quickly.

Description

A kind ofly intercept the method that trunk is transformed old mulberry field

Technical field

The present invention relates to a kind of mulberry sapling mode of reproduction, particularly a kind of method of take the new mulberry field of transformation that old mulberry tree is carrier.

Background technology

Area, Feng County, Jiangsu is the flat-bottomed land of washing away, depositing and form after changing its course in ancient the Yellow River, soil layer is all that thousands of kilometer washes away the alluvials such as mud fine sand stone of getting off and forms from ancient the upper reaches of the Yellow River, the husky earth layer of soil property, gas permeability is good especially, be rich in various mineral trace elements and various organic and inorganic nutrients fertilizer that plant growth needs in soil layer, so soil is very fertile.In addition, the Feng County warmer climate, make a clear distinction between the four seasons, and sunshine, abundance was applicable to the growth of growth, the especially mulberry tree of crops very much.

Mulberry tree is a kind of deciduous tree, well developed root system, and rudiment power is strong, looks fast, happiness light, branch density is medium; Can drought resisting resist cold, heatproof, wet, alkali resistant power is also larger.In addition, mulberry leaf are the main foodstuffs of feeding silkworm; Mulberry can furniture processed, farm implements, and can make the Minor Construction material; Paper mulberry bark can papermaking; Mulberry shoot can be compiled basket; Mulberries can be made wine.In sum, the good seeds that mulberry tree is not only water and soil conservation, fixes the sand, but also there is very high economic worth.

But the trunk of mulberry tree, mulberry the fist easily problem of old and feeble and its deadwood, withered stake are also very serious, add in addition the growing way variation, annual have 8%～15% mulberry field can step into old mulberry field ranks.In order to address this problem, we take to dig up again the plant method of little mulberry sapling of old mulberry tree to transform old mulberry field, but from again growing seedlings, grafting, be transplanted to the tree type and form and needed for 5 years～6 years, not only to buy mulberry sapling, and become the garden cycle too of a specified duration, virtually increased the cost that builds new garden.Therefore, how on cost-saving basis, to transform old mulberry field and become an important research topic.

Summary of the invention

In order to save time and to buy the seedling capital, we take to clip old mulberry tree trunk, and the method for impelling collar junction resting bud to sprout is transformed old mulberry field.Will select hot weather during cutting strunk, resting bud is active strong, highly beneficial to its germination and growth.Because of old root prosperity, the nutrient of absorption is fully concentrated again, and the new branch after cutting strunk is all more healthy and stronger.Under normal circumstances, every strain grows 1～3 healthy and strong buds and just can meet the demands.The base portion of new branch just can again grow new root after 1 year, became independent new individuality, and Lao Sang root originally is downright bad gradually, becomes the organic manure of new individuality, and after transforming 1 year～2 years, new branch can be formed the tree type.This method not only shortens the Liao Cheng garden cycle, has improved mulberry leaf, mulberry shoot output, but also saves Liao Jian garden cost, has increased economic benefit, can reach very soon new mulberry field effect.

The technical solution adopted for the present invention to solve the technical problems is that the method that this intercepting trunk is transformed old mulberry field is:

Before June 1, to mulberry tree, taked overhead 30cm～50cm place to clip trunk, if Sang Gan germinates, rear every 666.7 ㎡ in former mulberry field, lower than 850 strains, take two dry methods of forming, and reserve two limbs; If after Sang Gan germinates, every 666.7 ㎡ in former mulberry field, higher than 850 strains, take to go alone the method for forming, be conducive to regulate the density in mulberry field;

Two dry methods of forming are:

1. after cutting strunk, treat that mulberry tree collar junction sends forth branches, stay dryly at New shoot growth to 20cm～30cm place bud thinning overhead, stay 2～3 of buds, remove invalid bud, branch is stayed in pinching simultaneously, and every is stayed 2～3 shoot growths, forms the first limb;

2. pluck core when the first limb is grown to overhead 40cm～50cm place and stay bud, form then 5～6, effective branch, form the second limb, winter is overhead the 1.2m place winter cuts;

3. cut and cut down after the Second Year silkworm in spring is finished, overhead 70cm～80cm place summer is cut down, after sprouting grows, every is stayed 2～3 sproutings to produce branch as mulberry leaf, and every strain branch reaches 16～20, after the end of breeding silkworms, overhead 1.3m～1.5m place winter cuts, the tree type that has 10000 mulberry shoots as every 666.7 ㎡ mulberry fields is so just formed substantially, later annually at mulberry fist place, cuts in the summer, moves in circles;

Going alone the method for forming is:

1. after cutting strunk, treat that mulberry tree collar junction grows sprouting, stay dryly at the liftoff 15cm of sprouting～20cm place bud thinning, stay 1～2 of buds, remove invalid bud, pluck core simultaneously and stay branch, every is stayed 2～3 shoot growths, forms the first limb;

2. overhead pluck for the second time core and stay bud in 40cm～50cm place the first limb, form the second limb;

3. when the second limb is grown to overhead 70cm～80cm place, pluck for the third time core and stay bud, stay two buds on each limb, every strain mulberry tree is formed with 12～18 of mulberry shoots producing mulberry leaf, also reach the high yield standard that every 666.7 ㎡ mulberry fields have 10000 of effective mulberry shoots, the tree type is formed substantially, moves in circles every year later.

The invention has the beneficial effects as follows, by taking to clip old mulberry tree trunk, the method for impelling collar junction resting bud to sprout is transformed old mulberry field.Hot weather at a time when cutting strunk, resting bud is active strong, highly beneficial to germination and growth.Because the flourishing absorption of old root nutrient is fully concentrated, the new branch after cutting strunk is all more healthy and stronger again, and under normal circumstances, every strain grows 1～3 healthy and strong buds and just can meet the demands.The base portion of new branch again grew new root after 1 year, became independent new individuality, and Lao Sang root originally is downright bad gradually, becomes the organic manure of new individuality.This method not only shortens the Liao Cheng garden cycle, has improved output, but also saves Liao Jian garden cost, has increased economic benefit, can reach very soon new mulberry field effect.
