Problems solved by technology

[0002] Artificial emasculation hybridization at the bud stage is the main form of pepper hybrid seed production at present, but artificial emasculation hybrid seed production generally has problems such as serious shedding of pollinated flowers after hybridization, low fruit setting rate, and small number of pollinated fruits. The consequences are low efficiency of hybrid seed production, serious waste of human and financial resources, increased cost of seed production and low seed production

Embodiment 1

[0028] Application of a special flower-preserving smear agent for capsicum hybrid seed production in capsicum planting, a capsicum planting method, comprising the following steps:

[0029] 1) Preparation of special flower preservation smear:

[0030] During the peak period of pepper cross-pollination or before the fourth layer of flowers blooms, prepare a special flower-preserving smear mother liquor and store it at room temperature; when using, absorb a certain amount of mother liquor and mix it with pure water to make the special flower-preserving smear; The flower-preserving agent is prepared from 2,4-dichlorophenoxyacetic acid, gibberellic acid and water. In the special flower-preserving varnish, the content of 2,4-dichlorophenoxyacetic acid is 10 mg / L, and the gibberellin The content is 150 mg / L, and the balance is water;

Abstract

The invention discloses a special flower retention application agent for hybrid seed production of chili. The special flower retention application agent is prepared from 10-20 mg / L of 2,4-dichlorophenoxyacetic acid, 150 mg / L of gibberellic acid GA3 and the balance of water; the invention further provides an application of the special flower retention application agent. The special flower retentionapplication agent for hybrid seed production of chili and the application of the application agent have the benefits as follows: pedicel separation layer cell differentiation and separation layer formation are prevented effectively; falling off of pollinated flowers is prevented, and the fruit setting rate, single-plant fruit setting number and yield are increased; seedless fruits formed by parthenocarpy are prevented; the pollination efficiency is improved, the production cost is reduced, and the seed production yield is increased.

Description

technical field [0001] The invention relates to the technical field of capsicum seed production, in particular to a special flower-preserving smear for capsicum hybrid seed production and an application thereof. Background technique [0002] Artificial emasculation hybridization at the bud stage is the main form of capsicum hybrid seed production at present, but artificial emasculation hybrid seed production generally has problems such as severe shedding of pollinated flowers after hybridization, low fruit setting rate, and small number of pollinated fruits. The consequences are low efficiency of hybrid seed production, serious waste of human and financial resources, increased cost of seed production and low seed production. Preventing flower drop, increasing the fruit setting rate, the number of seeds set (the number of seeds per fruit) and the number of fruit set per plant are of great significance for improving the efficiency and yield of artificial hybrid seed production...
