Description
Technical Field
The invention relates to the technical field of peanut planting, in particular to a peanut middle-term accurate regulation and control method.
Background
Chinese peanuts are widely distributed and planted in various places. The main producing areas are Shandong, dong Liaoning, guangdong Leizhou peninsula, huang-Huai river areas and the coastal hills and sandy areas of the southeast coast. The areas such as the north of the northern China, the northern China of Su and the southern China, the Shandong peninsula, the southern Shanzhong hills, the Jidong \28390, the downstream of the river, the Yudong Huangpan area and the northern China of Su and Wan are key producing areas of peanuts in the northern China.
For peanuts, particularly summer peanuts, the traditional management concept is 'front promotion, central control and rear protection'. That is, growth promotion is mainly performed in the early stage after emergence of seedlings, urea or compound fertilizer is generally applied, or foliage fertilizer and bactericide for promoting growth are sprayed on the foliage, but as the diseases of the leaves in the seedling stage are not serious, the significance of spraying the bactericide on the foliage in the seedling stage is not great, and farmers generally have the problems of over-ensuring overground part growth and neglecting underground part growth, so that the root system development is not developed enough, the later-stage root system absorption is insufficient, plants are yellowed, the nutrition supply is insufficient, the diseases of the leaves are serious, and the like, and finally the problems can be solved by applying additional fertilizer to the leaves and applying pesticide to a large amount of the leaves; in the middle period, vigorous growth control, bactericide spraying on leaf surfaces and leaf surface fertilizers are mainly used, the plants are higher due to 'forward promotion', vigorous growth control is needed in the middle period, but the root system development is in a fixed position, vigorous growth control cannot promote the re-growth of the root system, and a vigorous growth control medicament and the leaf surface fertilizers are sprayed simultaneously, so that the vigorous growth control effect is poor due to the antagonistic action among medicaments, and secondary vigorous growth control is needed sometimes; the later stage is with foliage bactericide + leaf fertilizer as leading to, because leaf portion is carried to a large amount of nutrition, can make the leaf surface (including the redundant blade in many bottoms) keep bright green for a long time, although it is very good to see the disease prevention effect on the surface, in fact, a large amount of blades can consume a lot of nutrients, thereby lead to carrying the nutrition reduction of pod, the pod is full phase and need the extension, the fruit needs to be received late, and, because promote overground part growth excessively in earlier stage, root system development is not enough, thereby lead to the later stage root system absorbed quantity not enough to supply a large amount of blades and pod, can only maintain normal growth result through a lot of leaf portion spraying nutrition.
Therefore, how to precisely regulate the growth process of the peanuts is a problem which needs to be solved urgently by the technical personnel in the field.
Disclosure of Invention
In view of this, the invention aims to provide a peanut middle-stage accurate regulation and control method to solve the defects in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
the peanut middle-stage accurate regulation and control method specifically comprises the following steps: and (3) spraying naphthylacetic acid, uniconazole and pyraclostrobin on leaf surfaces in the late blooming period of the peanuts.
Further, the spraying amount of the naphthylacetic acid is 4.5-5 g/mu; the spraying amount of the uniconazole is 10-15 g/mu; the spraying amount of the pyraclostrobin is 18-20 g/mu.
The beneficial effect of adopting the further technical scheme is that the main purpose of the middle-term accurate regulation is as follows: controlling vigorous growth and flower, regulating vegetative growth and reproductive growth, removing the influence of ineffective flowers in later stage on nutrients, controlling plant height without vigorous growth, regulating substance transfer and promoting pod expansion. The effects are as follows: the stem is thick and strong, the root system is developed, the fruiting is consistent (the condition of big and small fruits does not appear), and the pod precocity is promoted.
Wherein,
the molecular formula of the naphthylacetic acid is C 12 H 10 O 2 It has the function of plant growth regulator. The naphthylacetic acid is absorbed by roots, stems and leaves, and can promote the development of peanut root systems and the maturity of peanut pods.
Uniconazole belongs to a broad-spectrum and high-efficiency plant growth regulator, has the functions of sterilization and weeding, is a gibberellin synthesis inhibitor, and has the advantages of good effect, short residual period and the like. Uniconazole has the functions of controlling vegetative growth, inhibiting cell elongation, shortening internodes, dwarfing plants, promoting lateral bud growth and flower bud formation and enhancing stress resistance. After being absorbed by the roots of plants, the uniconazole is conducted in the plants, has the functions of stabilizing the cell membrane structure and increasing the contents of proline and sugar, improves the stress resistance of the plants, and enables the plants to resist cold and drought.
Pyraclostrobin, chemical name N- [2- [ [1- (4-chlorophenyl) pyrazol-3-yl]Oxymethyl radical]Phenyl radical]-N-methoxy carbamic acid methyl ester of formula C 19 H 18 ClN 3 O 4 . Pyraclostrobin is strobilurin fungicide, can finally cause cell death by inhibiting mitochondrial respiration, and has the functions of protection, treatment and leaf penetration and conduction. The pyraclostrobin mainly is used for preventing and controlling various diseases caused by fungi on crops, and has good prevention and control effects on wheat powdery mildew and gibberellic disease. Pyraclostrobin has direct effect on pathogenic bacteria, and can induce physiological phenomena of many crops, especially grains, such as improving nitrogen absorption, promoting crop rapid growth, increasing crop yield, and achieving the purpose of high crop yield.
According to the technical scheme, compared with the prior art, the invention has the following beneficial effects:
the invention relates to subversion and innovation of the traditional management concept of peanuts, which mainly comprises the steps of establishing a corresponding regulation and control technology in the middle stage according to the growth and development rules of different peanut varieties, coordinating overground and underground growth, and integrating the accurate regulation and control technologies of 'full seedling, strong root, flower promotion, vigorous growth control and anti-aging' for the regulation and control of a middle-stage source bank.
