Description
Technical Field
The invention belongs to the technical field of green pepper planting, and particularly relates to a medicament and a method for promoting lignification of branches and flower bud differentiation of green pepper.
Background
At present, the planting area of zanthoxylum bungeanum in Sichuan province is 38 kilohm2The vast majority of the planting bases adopt paclobutrazol, chlormequat chloride and KH2PO4Or uniconazole + KH2PO4The lignification of the green pepper branches and the flower bud differentiation are promoted, and the planting owner has the defects of inaccurate staged control, improper selection and application of growth regulators, different application concentrations, wrong spraying positions, excessive dependence on medicaments and the like in the aspect of promoting the lignification of the green pepper, so that the large-area lignification of the green pepper, less flower bud differentiation, rare fruiting, dense cluster formation of flower ears and clusters, serious flower and fruit drop, or slow growth of the tree in the coming year are caused, most of the green pepper of the planting owner has few fruits, even no fruits, low economic benefit and serious loss.
The potential use hazard of paclobutrazol and chlormequat chloride is large: the application dosage and concentration of the main grower are difficult to control, and the probability of unsuccessful or incomplete lignification of branches is high. Secondly, the branches are easy to grow more vigorously and have more drooping branches, the tips are difficult to control and the flower bud differentiation is difficult to promote, and the cluster of the green pepper ears, the short cob and the serious flower and fruit dropping are easy to occur. Thirdly, the half-life period of the pesticide effect is long, so that the buds and the tips of the green Chinese prickly ash grow slowly after the green Chinese prickly ash is picked.
The single use of uniconazole also easily causes unsuccessful or incomplete lignification of branches, and greatly influences later flower bud differentiation.
Disclosure of Invention
Aiming at the prior art, the invention provides a medicament and a method for promoting lignification and flower bud differentiation of green pepper branches, and aims to solve the problems of inaccurate stage control, improper selection of a growth regulator, different application concentrations, wrong spraying position, excessive dependence on medicaments and the like of the existing green pepper planting technology.
In order to achieve the purpose, the invention adopts the technical scheme that: the medicament for promoting lignification and flower bud differentiation of the green pepper branches comprises the following components: uniconazole, 28-epihyperbrassin lactone, monopotassium phosphate, potassium, calcium, boron, magnesium, iron and zinc trace element water-soluble fertilizer and water.
The uniconazole has the function of controlling the growth speed of young shoots and promoting the conversion of vegetative growth to reproductive growth. Uniconazole has strong adhesion, good activity, easy absorption, durable drug effect, short half-life period, greenness and safety, and has remarkable effects on aging branches, shortening internodes and promoting nutrition conduction.
The 28-epihigh brassinolide is used as various channels for smooth nutrient transportation, is always present in the whole physiological period of plants, distributes and regulates the plant life substances according to different physiological periods of green peppers, promotes photosynthesis, nutrient conversion and absorption of the plants, systematically and reasonably helps the plants to adapt to the external environment change, enables the plants to smoothly complete various physiological periods, and accordingly achieves the effects of high yield, high yield and improvement of the quality of crops.
The monopotassium phosphate mainly promotes the branches to turn from green to brown, promotes the roots, stems and leaves of plants to grow faster, leads flower buds to differentiate faster, and leads the root system to develop and new branches and leaves to grow healthily. The potassium-calcium-boron-magnesium-iron-zinc trace element water-soluble fertilizer provides trace elements required by flower bud germination of branches, promotes the robust root system, prevents leaves from greening and yellowing, prevents flowers from being too fruity and the like.
The potassium-calcium-boron-magnesium-iron-zinc trace element water-soluble fertilizer has the functions of providing trace elements required by flower bud germination of branches, promoting the robust root system, preventing the leaves from being greenish and yellow, preventing flowers from being too fruity and the like.
The synergistic effect of the four is as follows: when the uniconazole reaches the tip control growth speed, the brassin is rapidly distributed according to the amount of nutrients and hormones required by each reproductive organ as required, and channels are rapidly cleared, and the monopotassium phosphate is in a reasonable micro-domain environment at this time, so that branches are rapidly lignified. If the branches are in the vegetative growth stage because of the lack of uniconazole, the brassin cannot distribute nutrients and hormones according to the requirements of various organs, the transportation channel is possibly blocked, and the lignification speed of the branches is slow due to the monopotassium phosphate. Uniconazole plays a braking role. The potassium-calcium-boron-magnesium-iron-zinc trace element water-soluble fertilizer provides trace elements required for lignification of branches and germination of flower buds, and makes up the trace elements in soil; if the brassin is lack, a material distribution, scheduling and transportation system is lacked, and if the potassium dihydrogen phosphate is lacked, the brassin cannot be distributed, scheduled and transported, so that the close cooperation of the four systems forms a large system with a high yield foundation, and if the four systems are lacked, the phenomenon that the lower branches have few or no results in production can occur.
The invention also provides a method for promoting lignification and flower bud differentiation of green pepper branches treated by using the medicament, which comprises the following steps:
(1) medicament regulation: regulating the branches 5 times by using the pesticide in the middle and last ten days of 7 months to 10 last days of 10 months, and preparing the pesticide for application in times when the lengths of the branches are respectively 20cm-40cm, 40cm-60cm, 60cm-80cm and 80-120 cm;
(2) manual adjustment: carrying out 2-3 times of layering before and after layering; removing the non-lignified apical portion in the middle of 11 to 12 months; and in 1-2 months, shallow intertillage is carried out on the surface soil in the lower line of the tree disk once, and then the flower promoting fertilizer is applied.
On the basis of the technical scheme, the invention can be improved as follows.
Further, the medicament adjustment is carried out in a full-branch spraying mode for the first time, and the used medicament is sprayed every 667m2The formula is calculated by preparing 40ml of 10 percent uniconazole suspending agent, 20ml of 0.004 percent 28-epibrassinolide aqua, 50g of 98 percent monopotassium phosphate and 30kg to 40kg of water.
The first-time medicament regulation has the functions of controlling the growth of growing points, enabling nutrients to flow backwards, supplementing endogenous hormones in plants, enabling the surfaces of branches to be changed from green to brown, creating conditions for flower bud differentiation and finally enabling the lower parts of the branches to be full of fruit ears.
Further, the medicament adjustment is carried out in a full-branch spraying mode for the second time, and the used medicament is sprayed every 667m2The formula is calculated by preparing 60ml of 10 percent uniconazole suspending agent, 20ml of 0.004 percent 28-epibrassinolide aqua, 70g of 98 percent monopotassium phosphate and 30kg to 40kg of water.
The second-time agent regulation has the functions of controlling the growth speed of the newly-extracted branch tips, enabling nutrients to flow backwards, supplementing endogenous hormones in plants, changing the skins of new branches from green to brown, creating conditions for flower bud differentiation, and enabling the new branches to sequentially bloom and bear fruits within the range of 40cm branches at the lower part.
Further, the medicament adjustment is carried out in a full-branch spraying mode for the third time, and the used medicament is sprayed every 667m2Calculated from 10% uniconazole suspension agent 80ml, 020ml of 004 percent 28-epi-high brassinolide aqua, 90g of 98 percent monopotassium phosphate and 30kg to 40kg of water.
The third medicament adjustment has the effects of controlling the growth speed of the branch tips of the new branches, enabling nutrients to flow backwards, supplementing endogenous hormones in plants, enabling the epidermis of the new branches to be changed from green to brown, creating conditions for flower bud differentiation, and enabling the new branches to sequentially bloom and bear fruits within the range of the branches 60cm below the new branches.

(5) Forced old people collection: forcibly aging branches with lignification degree of less than 80% in 11 months, wherein the used medicament is used per 667m2Is prepared by adding 160ml of 10 percent uniconazole suspending agent, 20ml of 0.004 percent 28-epihomobrassinolide aqua, 140g of 98 percent monopotassium phosphate and 35kg of water.
2. Manually adjusted
(1) And (3) branch pressing: pressing branches for 2 times before and after branch fixing, stopping over-nutrition of the branches to help the branches lignified, enabling the sunlight to irradiate uniformly, and enabling the flower bud differentiation tip and the bottom to be uniform;
(2) pinching: removing the non-lignified apical portion in the middle of 11 to 12 months to promote flower bud differentiation;
(3) cultivating: in 1-2 months, the surface soil in the lower line of the tree disk is ploughed once, and then the flower promoting fertilizer is applied.
Example 2
The adjustment time of the medicament in the example 1 is changed into that the medicament is prepared and applied by times when the lengths of branches are respectively 20cm, 40cm, 60cm and 80cm, the water consumption for preparing the medicament is adjusted to be 30kg each time, and the rest is the same as the example 1.
Example 3
The adjustment time of the traditional Chinese medicine preparation in the example 1 is changed into that the preparation is applied by times when the lengths of branches are respectively 40cm, 60cm, 80cm and 120cm, the water consumption for each preparation is adjusted to 40kg, and the rest is the same as that in the example 1.
Comparative example 1
The fourth-time old medicament obtained in the example 1 is the same as the medicament obtained in the example 1 except that the potassium-calcium-boron-magnesium-iron-zinc microelement water-soluble fertilizer is removed.
Comparative example 2
The uniconazole in the fourth-time old drug in example 1 was changed to paclobutrazol, and the rest was the same as in example 1.
Comparative example 3
The 28-epibrassinolide in the fourth-time aged drug of example 1 was changed to diethyl aminoethyl hexanoate, which was the same as that of example 1.
Examples of the experiments
The young sprout extraction conditions of the green Chinese prickly ash are investigated, and the specific operations are as follows:
during the investigation, fixed-point plant determination is carried out, and east, west, south and north of each pricklyash tree are respectively investigated for 1 new shoot. When 55-60% of young shoots of the whole plant are extracted by 30-35 cm and 55-60% of young shoots of the whole plant are extracted by 55-60 cm, only the length of branches is investigated; when 55-60% of young shoots of the whole plant grow 85-90 cm, the length, the number of flower buds per 12cm and the lignification degree of the shoots (the proportion of black parts in the whole young shoots) are investigated. 5 plants were investigated per cell, the mean was calculated and the shoot control effect was evaluated.
The optimal tip control effect needs to simultaneously meet 3 conditions: the length of the branches is 1.2-1.4 m, the lignification degree accounts for 60-70%, and the number of effective flower buds per 12cm is about 4-5. Under the condition, the later period management is more convenient, and the yield of the green pepper is improved.
The optimal node range of the 3 branches is the critical point of vegetative growth and reproductive growth of the pepper branches, if the branches are short when a medicament is used, particularly for the first time, the length of the whole pepper sprout emergence can be seriously influenced, the ideal length cannot be reached, and the yield of the pepper is seriously influenced. If the branches are too long when the Chinese prickly ash tree seedling growing machine is used, the yield of Chinese prickly ash can be seriously influenced (the vegetative growth of the Chinese prickly ash branches is too vigorous, the reproductive growth is seriously reduced, the branches are seriously too long, the tree vigor of the Chinese prickly ash is reduced, and the plant diseases and insect pests are increased).
And in the process of yield measurement investigation, 5 plants are investigated in each cell, the total number of branches and yield measurement are investigated, and the average effective number of branches and the average plant yield are calculated.
The results of the experiment are shown in table 1.
