Referring to the drawings, fig. 1 is a schematic diagram of the efficient cutting seedling method of the yellow fruit of the present invention.

The invention relates to a high-efficiency cutting seedling method for Huangjingguo, which is characterized by comprising the following steps of:

step 101, deep turning the seedbed, adding coconut coir and sand into the seedbed, uniformly mixing, adjusting the length, width and height of the seedbed, and finally, using a diluted broad-spectrum bactericide to soak the seedbed for standby, and waiting for cuttage.

In the concrete implementation, the seedbed is deeply turned for 22-28cm, then coconut husk and sand with the mass ratio of 2:1 are added into the seedbed, after uniform mixing, the seedbed is more loose and breathable and has proper humidity, cutting shoots are facilitated to root, the length of the seedbed is adjusted to be 2.5-3.5m, the width of the seedbed is 0.8-1.2m, the height of the seedbed is adjusted to be 15-20cm, and finally 1200-1800 times carbendazim solution is used for drenching the seedbed for standby, and cutting is waited for.

By setting the size of the seedbed, the management is facilitated, for example, the range of water showering of the shower is 0.4-0.6m when the shower is manually taken each time, and the shower is performed half at first and then the other half at the same time when the shower is conveniently operated each time; the small arched shed is convenient to construct, and the width of the arched shed formed when the arched shed is made is 1-1.2m because the arch bars used by the small arched shed are 2.2m in length, so that a seedbed with the width of 0.8-1.2m is selected. Furthermore, coconut coir is used: sand=2:1 is mixed with the deep-ploughed red loam, so that the seedbed is more loose and breathable, and rooting is facilitated. And the carbendazim solution is poured on the seedbed for sterilization treatment, so that the diseases, insects, germs and the like in the seedbed are killed, and the rot or non-survival of the base of the cutting due to the infection of the base of the cutting with the diseases, insects and the like is reduced.

Step 102, selecting yellow crystal seedlings which are vigorous in visible light and semi-lignified with leaves, then cutting branches, cutting the branches into cutting slips with two leaves, enabling an upper cutting opening to be smooth, and enabling a lower cutting opening to be inclined.

In the concrete implementation, the branches with the stem thickness of 3-7mm are cut, and then the branches are cut into cutting slips with two leaves and 6-9cm long, the upper cutting opening is smooth, and the lower cutting opening is a 45-degree inclined plane.

The diameter of the branches with the stem thickness of 3-7mm is proper, and the cutting heads with the specification have strong activity and vigorous activity. The lower shearing opening is designed to be 45-degree inclined plane, so that the base part of the cutting slip can be in contact with rooting agent solution in a large amount, the survival rate of the cutting slip is improved, and the cutting slip is convenient to cut; the upper cutting opening is smoothly arranged, so that the upper cutting opening is prevented from being too sharp, and the hand is prevented from being scratched in the cutting process; 2 leaves are reserved for each section of cutting, photosynthesis can be carried out, nutrition and nutrients can be provided, and survival of the cutting after cutting is facilitated.

Step 103, immersing the cutting slips in the rooting agent solution A for 3-5min; wherein, 0.5g of naphthalene acetic acid and 0.5g of indolebutyric acid are dissolved in 3mL of ammonia water with the concentration of 25%, then the naphthalene acetic acid and the indolebutyric acid are added with water to obtain 500mL of mixed solution, namely, 1mg/mL of naphthalene acetic acid and 1mg/mL of indolebutyric acid are prepared, 0.1g of riboflavin and 0.05g of zeatin nucleoside are added into 500mL of mixed solution, and the rooting agent solution A is obtained after uniform mixing.

In the concrete implementation, the cutting base part is immersed in the rooting agent solution A for 3-5min in a proportion of 1-2 cm. Therefore, the base part of the cutting slip is fully immersed in the rooting agent solution A, so that survival and rooting of the cutting slip after cutting are facilitated.

The zeatin nucleoside can strengthen physiological activities of the cutting slips, accelerate growth and differentiation of cut cells of the cutting slips, form a large number of root primordia, break through outwards, accelerate healing, promote formation of adventitious roots and grow and elongate. The riboflavin protects the basal part of the cutting pin from the influence of external bad environment, can provide partial auxiliary substances required by the formation of adventitious roots, can synthesize endogenous hormone of the cutting pin to promote callus, shortens rooting time and improves rooting rate of the cutting pin.

The formation of adventitious roots of the yellow pod cutting belongs to the rooting of calli, which mainly originate from cambium and vascular ray parenchyma cells. In the research, the main factors of the cutting rooting of the yellow fruits are calli, a large number of researches show that the zeatin nucleoside can promote the formation of the calli and the elongation growth of adventitious roots, and the researches show that the riboflavin can promote the formation of the adventitious roots. Therefore, the cutting is treated by the zeatin nucleoside and the riboflavin in combination with the rooting agent, so that the cutting of the yellow fruit is rapidly rooted and the propagation coefficient is enlarged.

104, cutting the cutting slips in a seedbed, and then thoroughly watering with a solution B, wherein the solution B can be directly absorbed and utilized by the cutting slips of the yellow crystal fruits, has quick absorption and remarkable fertilizer efficiency, can effectively provide nutrition and is beneficial to rooting of the cutting slips; sufficient moisture is also provided to keep the seedbed moist. Meanwhile, a small arch shed is built, a white film is covered, and finally the periphery of the film is compacted, so that the small arch shed is sealed and airtight; wherein, 3g of seaweed fertilizer is taken and dissolved in 15kg of water to obtain solution B.

In the concrete implementation, cutting the cutting slips in a seedbed, wherein the cutting slips are 10-15cm in distance and 1-2cm in depth, then pouring the cutting slips thoroughly by using the solution B, building a small arch shed, wherein the arch height is 50-90cm, the arch width is 80-120cm, coating a white film, and finally compacting the periphery of the film to ensure that the small arch shed is sealed and airtight.

Further, in order to avoid direct irradiation, a greenhouse with the arch height of 1.5-2.5m is built on the small arch greenhouse, and a shading net is covered, so that moisture evaporation of cutting shoots and seedbeds is reduced. The shading net can be 9 needles, and the light transmittance is 75%.

Step 105, spraying the mixed solution of the solution B and the broad-spectrum bactericide once every 2-4 days after cutting, and mixing the mixed solution: 15kg of solution B are mixed with 15ml of carbendazim; after cutting for 30 days, spraying the mixed solution of the solution B and the solution C every 2-4 days, wherein the mixing mode is as follows: adding the solution C into 15kg of the solution B to obtain a mixed solution; wherein, 1.5g of the indole acetic acid was dissolved in 5ml of 95% ethanol to obtain a solution C. .

The concentrations of the above raw materials used are respectively: naphthalene acetic acid 0.8-1.2mg/mL, indolebutyric acid 0.8-1.2mg/mL, riboflavin 0.1-0.3mg/mL, zeatin nucleoside 0.05-0.0.15mg/mL, indoleacetic acid 0.05-0.15mg/mL, and seaweed fertilizer 0.1-0.3mg/mL.

In the concrete implementation, after cutting, the mixed solution of the solution B and the carbendazim is sprayed once every 2-4 days for 7-15 times, which is favorable for providing nutrition and moisture, can effectively sterilize, prevent the base of the cutting slip from rotting and greatly improve the survival rate of the cutting slip; after cutting for 30 days, spraying the mixed solution of the solution B and the solution C for 7-12 times every 2-4 days, which is favorable for strengthening roots and forming a large number of adventitious roots and growing the roots, so that the roots are strong and developed, nutrients and moisture can be effectively provided, and the survival rate of cutting slips can be improved.

And 106, after rooting, if the temperature in the greenhouse is too high, opening and ventilating the two ends of the film, avoiding the too high humidity temperature of the small arch greenhouse, preventing the cutting from being infected by diseases, after rooting for 10-20 days, uncovering the film for hardening seedlings, and after rooting for 25-35 days, transplanting the film into a field.

Step 202, selecting yellow crystal seedlings with vigorous visible light and semi-lignified leaves, shearing branches with the stem thickness of 3-7mm, shearing the branches into cutting slips with two leaves and the length of 6-9cm, enabling an upper shearing opening to be smooth, and enabling a lower shearing opening to be 45-degree inclined plane.

Step 203, immersing the cutting base 1-2cm into the rooting agent solution A for 3-5min. Wherein, 0.5g of naphthalene acetic acid and 0.5g of indolebutyric acid are dissolved in 3mL of 25% ammonia water, then the naphthalene acetic acid and the indolebutyric acid are added with water to obtain 500mL of mixed solution, and then 0.1g of riboflavin and 0.05g of zeatin nucleoside are added into the 500mL of mixed solution, and the rooting agent solution A is obtained after uniform mixing.

And 204, cutting the cutting slips in a seedbed, wherein the cutting pitch is 12cm, the depth of the cutting slips is 1.5cm, then, pouring the cutting slips thoroughly by using the solution B, simultaneously building a small arch shed, wherein the arch height is 70cm, the arch width is 100cm, coating a white film, and finally compacting the periphery of the film to ensure that the small arch shed is sealed and airtight. Wherein, 3g of seaweed fertilizer is taken and dissolved in 15kg of water to obtain solution B.

Step 205, spraying the mixed solution of the solution B and the carbendazim once every 2-4 days after cutting, and continuously 10 times, wherein the mixed solution is mixed in the following way: 15kg of the solution B was added with the solution C to obtain a mixed solution. Spraying the mixed solution of the solution B and the solution C for 8 times every 2-4 days after cutting for 30 days; the mixing mode of the mixed solution is as follows: adding the solution C into 15kg of the solution B to obtain a mixed solution; wherein, 1.5g of the indole acetic acid was dissolved in 5ml of 95% ethanol to obtain a solution C.

TABLE 1 data recording table of yellow crystal heading

Analysis of results:

1. 15d after cutting in experimental examples, calli are formed on a large scale; the phloem of the basal part of the cutting pin begins to expand; the cuttage rooting rate is 95%, the average root number is 12 roots/plant, the average root length is 46.08mm, the longest root length is 63.37mm, the average root diameter is 2.96mm, and the maximum root diameter is 3.57mm.

Comparative example 1 calli were formed on a large scale 28 days after cutting; further separation at the cutting edge of the cutting edge base; the cuttage rooting rate is 65%, the average root number is 5 roots/plant, the average root length is 25.53mm, the longest root length is 39.32mm, the average root diameter is 2.32mm, and the maximum root diameter is 2.51mm.

Comparative example 2 survival rate was 12%.

From the results, comparative example 2 shows very low rooting survival rate.

2. Although the rooting survival rate of the yellow fruits is effectively improved in comparative example 1, the formation of adventitious roots at the base of the cutting shoots is reduced because the riboflavin and the zeatin nucleoside are not added, the growth of the roots is greatly slowed down, and the roots still do not survive in a certain proportion; the cutting of the experimental example greatly improves the formation of adventitious roots and the survival rate of the cutting, and has long, strong and developed root systems.

The treatment effect is best by adding riboflavin and zeatin nucleoside, callus and adventitious roots can be formed rapidly, growth and elongation of the adventitious roots are promoted, the cuttage rooting rate is 95%, and the number of average root systems is 12 per plant. Therefore, under the synergistic effect of the riboflavin and the zeatin nucleoside, the formation of the cutting callus and the growth and elongation of adventitious roots of the cutting callus can be promoted.
