Abstract

The invention discloses a double-tree planting method of mulberry and belongs to the technical field of mulberry planting. The double-tree planting method of mulberry includes transversely planting two plants in one hole according to the planting density of 450-500 holes per 666.7m<2>; and pruning in second or third year by low-headed cultivating to cultivate the mulberry in fist form so as to form first stems, second stems and branches. By enlarging the spacing in rows and holes, field interplanting is facilitated, ventilation of mulberry fields is improved, and leaf quality is improved. Light, heat and space resources in mulberry fields are fully utilized, land utilization rate is increased, mulberry quality is improved, labor is fully utilized, mulberry field income is increased, field production and mechanical operation are more facilitated, labor productivity is improved, and income is increased for silkworm raisers.

Description

The two strain cultivation method in mulberry tree one cave

Technical field

The present invention relates to a kind of mulberry cultivation method of applicable interplanting, belong to mulberry tree planting technology field.

Background technology

Mulberry field is to produce mulberry leaf, and main purpose produces mulberry leaf to be used for sericulture cocooning and to reel off raw silk from cocoons, and obtains economic benefit.Therefore mulberry field income is more single.And mulberry field solid interplanting can make full use of space and the sunshine in mulberry field, improve land utilization rate, increase mulberry field cropping index and output capacity, improve field, mulberry field ecotope, promote the income of silkworm raiser.But traditional mulberry tree High Yield Cultivation Pattern is generally every 666.67 square metre of 850 ~ 1000 strain, effective mulberry shoot number 10000 ~ 12000, namely often say high-yield condition " thousand strains ten thousand " on producing, leaf yield is more than 2300 kilograms, and strain, line-spacing are respectively 1.6 ~ 1.3 meters, 0.49 ~ 0.51 meter.This situation is not only not suitable for production and the operation of interplanting, is more not suitable for the operation of small-scale agricultural machinery.And Summer Field closing are serious, can not ventilation and penetrating light, affect photosynthesis, make mulberry leaf food value of leaf degradation.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art part, the invention provides the two strain cultivation method in a kind of mulberry tree one cave, be more applicable to interplanting, can improve land utilization rate, improve labor productivity, improve quality of mulberry leaf, field of being more convenient for produces and mechanically actuated.

The present invention is achieved through the following technical solutions: the two strain cultivation method in a kind of mulberry tree one cave, it is characterized in that: 1) first choose mulberry sapling, mulberry sapling line-spacing of planting is 1.8 ~ 2.2 meters, cave is apart from 0.74 ~ 0.67 meter, laterally plantation two strains of every cave, plantation density is every 666.7 square metre of 450 ~ 500 cave, adopts lowly dryly to form method;

2) after First Year is planted, cut dry in overhead 15 ~ 20 centimeters, when the sprouting sprouted grows to 10 ~ 15 centimetres, outside every strain, neat, healthy and strong, the uniform sprouting of adnation position 2 ~ 3 of selecting and remain, removes all the other;

3) Second Year, before mulberry tree germinates, liftoff 30 ~ 50 centimeters spring are cut down, and form the first branch, and stay 2 ~ 3 young sprout growths outside every root branch upper end after germinateing, all the other remove, and 4 ~ 6 branches are formed in every strain;

4) the 3rd year, silkworm in spring was cut ahead of time after terminating and cuts down, and cutting down from 40 ~ 60 centimeters summers, formed the second branch; 2 ~ 3 blastogenesis of selecting and remain of every branch are long, and 8 ~ 12 branches are formed in every strain;

5) annual all cutting at branch base portion is cut down later, utilizes resting bud to grow, forms mulberry fist; Annual after silkworm in spring is terminated, cut at Sang Quanchu and cut down, every utilizes resting bud to grow 2 ~ 3 mulberry shoots, and autumn end carries out horizontal top clipping, moves in circles thus, can cultivate into the High Productive Mulberry Field of the two strain in a cave of applicable interplanting.

Improve as one, after First Year plantation, if the sprouting outside every strain is less than 3 buds, can pluck the process of core bifurcated when young shoot grows to 10cm to its top, thus turn out 3 the first limbs, winter is the horizontal top clipping of 80 ~ 100cm overhead.

The invention has the beneficial effects as follows: the present invention, because row, cave are apart from strengthening, not only makes interplanting convenient, such as hand tractor, little Bai dragon rural area machine can be produced with entering, more because cave, distance strengthen, improve mulberry field ventilation and penetrating light condition, leaf quality is increased.The present invention not only makes every 666.7 square metres of effective numbers in mulberry field reach 10000 ~ 12000, and mulberry yield and quality all increase.The present invention is applicable to interplanting, makes full use of mulberry field light, heat and space resources, improves land utilization rate, improve quality of mulberry leaf, make full use of labour, improve mulberry field income, be more convenient for field produce and mechanically actuated, improve labor productivity, add silkworm raiser income.

Accompanying drawing explanation

The present invention is further described according to drawings and embodiments below.

Fig. 1 is that the present invention grows flow chart.

Embodiment

Below in conjunction with embodiment, the present invention is further described.

As shown in Figure 1, in figure, 1 ~ 3 First Year does rear limb growth figure surely, and 4 ~ 5 Second Year spring cut down rear first limb growth figure, and 6 ~ 7 the 3rd year summer cut down rear second limb growth figure, and a is the first limb, and b is the second limb, and c is branch.

The two strain cultivation method in a kind of mulberry tree one cave, comprises the following steps:

1. selection nursery stock is sturdy, size is even, hibernaculum is full, root system is good, the mulberry sapling of anosis worm is planted, and cave, line-spacing are 0.70 meter × 2 meters, and density is 480 cave/666.7 square metre, laterally plantation 2 strains of every cave.

2. after planting, overhead 15 centimetres cut off and surely do.When mulberry bud grows to 15cm, bud thinning is carried out after calmly doing, 3 neat, healthy and strong, uniform 3 sproutings of adnation position are chosen outside every strain, all the other are all extractd, if less than 3 buds, the process of core bifurcated can be plucked to its top when young shoot grows to 10cm, thus turn out 3 the first limbs, winter is the horizontal top clipping of 80 ~ 100cm overhead.

3. Second Year, before mulberry tree germinates, overhead the 35cm place spring is cut down, and forms the first limb, and after germinateing, the 2 young sprouts growths of selecting and remain of every root branch upper end are even, the New shoot growth in basically identical outside, direction, and all the other remove, and winter is at overhead 1.2 meters of horizontal top clippings in.

4. the 3rd year, after silkworm in spring is terminated, cut down in the liftoff 55cm place summer, form 6 the second branchs.2 blastogenesis of selecting and remain of every branch are long, and 12 branches are formed in every strain.All cut at branch base portion every year later and cut down, form fist formula.

5. annual after silkworm in spring is terminated, cut at Sang Quanchu and cut down, every utilizes resting bud to grow 2 mulberry shoots, and amount to 12 mulberry shoots, autumn end carries out horizontal top clipping.Move in circles thus.The High Productive Mulberry Field of the two strain in a cave of applicable interplanting can be cultivated into.

6., because cave, line-spacing are larger, mulberry tree space is large, can execute urea 8kg respectively in spring, season in autumn two than conventional mulberry field more.
