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 methods in mulberry tree one cave

Technical field

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

Background technology

The mulberry field to be producing mulberry leaf as main, and main purpose is to produce the mulberry leaf cocooning that is used for breeding silkworms to reel off raw silk from cocoons, and obtains economic effect one benefit.Therefore the mulberry field income is more single.And the three-dimensional interplanting in mulberry field can take full advantage of space and the sunshine in mulberry field, improves land utilization rate, increases mulberry field cropping index and output capacity, improves field, mulberry field ecotope, promotes silkworm raiser's income.But traditional mulberry tree High Yield Cultivation Pattern generally is per 666.67 square metre of 850～1000 strain, effectively mulberry shoot is several 10000～12000, often say high-yield condition " ten thousand of thousand strains " on namely 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 not only is not suitable for production and the operation of interplanting, more is not suitable for the operation of small-scale agricultural machinery.And the field closing are serious summer, can not ventilation and penetrating light, affect photosynthesis, and 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 methods in a kind of mulberry tree one cave, more be fit to interplanting, can improve land utilization rate, improved labor productivity, improved quality of mulberry leaf, the field of being more convenient for produces and mechanically actuated.

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

2) after First Year is planted, cut driedly in 15 ~ 20 centimeters overhead, long during to 10 ~ 15 centimetres when the sprouting that sprouts, in every strain outside, 2 ~ 3 of neat, healthy and strong, the uniform sproutings of adnation position of selecting and remain remove all the other;

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

4) the 3rd year, cut ahead of time after silkworm in spring is finished and cut down, cutting down from 40 ~ 60 centimeters summers, form 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) all cut at the branch base portion and cut down every year after, utilizes the resting bud growth, forms the mulberry fist; Annual after silkworm in spring is finished, cut at Sang Quanchu and to cut down, every is utilized resting bud to grow 2～3 mulberry shoots, and autumn end is carried out horizontal top clipping, moves in circles thus, can cultivate into the High Productive Mulberry Field of the two strains in a cave that are fit to interplanting.

As a kind of improvement, after the First Year plantation, if the sprouting in every strain outside less than 3 buds, can be plucked the core bifurcated to its top and process, thereby turn out 3 the first limbs when young shoot is grown to 10cm, winter is the horizontal top clipping of 80 ~ 100cm overhead.

The invention has the beneficial effects as follows: the present invention is because row, the cave is apart from increasing, not only makes interplanting convenient, such as hand tractor, Xiao Bai dragon rural area machine can be produced with advancing, more owing to cave, distance strengthen, improve mulberry field ventilation and penetrating light condition, so that leaf quality increases.The present invention not only makes per 666.7 square metres of effective numbers in mulberry field reach 10000 ~ 12000, and mulberry yield and quality all increase.The present invention is fit to interplanting, takes full advantage of mulberry field light, heat and space resources, improves land utilization rate, improve quality of mulberry leaf, taken full advantage of the labour, improved the mulberry field income, being more convenient for, the field produces and mechanically actuated, has improved labor productivity, has increased silkworm raiser's income.

Description of drawings

The present invention is further described with embodiment with reference to the accompanying drawings for the below.

Fig. 1 is the present invention's flow chart of growing.

Embodiment

The present invention is further described below in conjunction with embodiment.

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

The two strain cultivation methods in a kind of mulberry tree one cave may further comprise the steps:

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

2. after planting, overhead 15 centimetres cut off surely and to do.Carry out bud thinning when treating mulberry bud length to 15cm after fixed the doing, choose 3 neat, healthy and strong, uniform 3 sproutings of adnation position in every strain outside, all the other are all extractd, if less than 3 buds, can pluck the core bifurcated to its top when young shoot is grown to 10cm processes, thereby turn out 3 the first limbs, winter is the horizontal top clipping of 80～100cm overhead.

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

4. the 3rd year, silkworm in spring was cut down at liftoff 55cm place after finishing in the summer, forms 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 the branch base portion every year later on and cut down, form the fist formula.

5. annual after silkworm in spring is finished, cut at Sang Quanchu and to cut down, every is utilized resting bud to grow 2 mulberry shoots, amounts to 12 mulberry shoots, and autumn end is carried out horizontal top clipping.Move in circles thus.Can cultivate into the High Productive Mulberry Field of the two strains in a cave that are fit to interplanting.

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