Abstract
The invention discloses a method for controlling flowers, controlling plumping fruits and increasing yield of peanuts, which specifically comprises the following steps: 1) applying nitrogen nutrient solution after the first pair of lateral branches of the peanuts grow, delaying the flowering time and promoting the plant morphogenesis; 2) spraying hormone nutrition inducing liquid 30 days after the emergence of the flower, and inducing concentrated flowering; 3) measures for reducing ineffective flowers and promoting plumpness: spraying a flowering inhibitor 20 days after flowering to promote fruiting; 4) spraying sterilization nutrition combination 40 days after blooming, and prolonging the functional period of the leaves. The invention provides a method for controlling peanut blossom, controlling peanut plumping and increasing peanut yield.
Description
Technical Field
The invention belongs to the high technical field of agriculture, and particularly relates to a method for controlling flowers, controlling plumping fruits and increasing yield of peanuts.
Background
The peanut is an important oil crop in China, guarantees the safety of edible oil in China, and has great significance for increasing the income of farmers.
As the peanut production is greatly influenced by natural conditions, the problems of uncoordinated vegetative growth and reproductive growth, large difference between flowering period and flowering amount, unconcentrated fruit, poor plump rate, blighted fruit, germinated fruit and rotten fruit rate, non-uniform pod maturity, unstable peanut yield and poor commodity quality often occur, so that the economic benefit of peanut production is reduced. According to research, the flowering of plants is influenced by temperature, nutrients, water, photosynthetic performance and endogenous hormones, and the flowering and fructification of the plants can be influenced to different degrees by adjusting the conditions through human intervention.
Therefore, the technical personnel in the field need to solve the problem that the fertilization method can effectively adjust the peanut flowering rule, realize the concentrated flowering and the concentrated fruiting and increase the peanut plumpness rate and achieve the aims of increasing the yield and the income of the peanuts.
Disclosure of Invention
In view of the above, the invention provides a method for controlling flowering, controlling plumping and increasing yield of peanuts, which controls flowering of peanuts by formula fertilization and hormone induction regulation in a key period, reduces early and late flowering, increases middle flowering, realizes centralized flowering, centralized fruiting and increases the plumpness of peanuts, and achieves the purposes of increasing yield and income of peanuts.
In order to achieve the purpose, the invention adopts the following technical scheme:
