Problems solved by technology

Under natural conditions, the pods of the same plant have great differences in maturity due to their different insertion positions. Usually, the needles with higher insertion positions cannot enter the soil in time because of their distance from the ground, and eventually fail to develop. To mature pods, resulting in the ineffective use of some fruit needles
In peanut interspecific hybrid breeding, interspecific hybrids have low fertility, and the formed fruit needles are easy to abort. The rescue of retired embryos requires high conditions and a large workload, and the success rate is low. On the other hand, the offspring of interspecific hybrids grow Lush, the formed fruit needles cannot enter the soil, and the plant has few pods

Embodiment 1

[0023] The technical scheme adopted in this embodiment is:

[0024] The method for promoting the aboveground fruiting of peanut needles is realized by the following steps: preparing a special needle culture substrate, wrapping the aboveground needles with a plastic film, and carrying out non-isolated culture of the needles; the special needle culture substrate is prepared by Slaked lime, gel and seedling substrate are mixed according to the mass ratio of 1:10:40. The gel is made by mixing water-retaining agent and water at a ratio of 1:300. The seedling-raising substrate contains organic matter ≥ 30%, pH value 5.5-7.5, and total nutrients ≥ 4%.

[0025] The plastic film is black and completely opaque, and cut into 15cm×15cm squares for later use.

[0026] After sowing peanuts, adopt conventional field management methods for water and fertilizer management and cultivating soil. During the flowering and needle stage, select fruit needles that are not buried in the soil and are ...

Embodiment 2

[0028] The difference between the technical solution adopted in this embodiment 2 and embodiment 1:

[0029] The prepared special fruit needle culture substrate is made by mixing slaked lime, gel and seedling cultivation substrate according to the mass ratio of 1:23:93; the gel is made of water-retaining agent and water according to the mass ratio of 1:350 Prepared by mixing.

[0030] In the stage of flowering and needle setting, select fruit needles with a length of 3 to 4 cm that have not been buried in the soil, and wrap the fruit needles with a black opaque plastic film wrapped with 27 g of special fruit needle culture substrates.

Embodiment 3

[0032] The technical scheme that present embodiment 3 adopts is different from embodiment 1:

[0033] The prepared special fruit needle culture substrate is made by mixing slaked lime, gel and seedling cultivation substrate according to the mass ratio of 1:8:30; the gel is made of water-retaining agent and water according to the mass ratio of 1:250 Mix well to make.

[0034] In the stage of flowering and needle setting, select fruit needles with a length of 3 to 4 cm that have not been buried in the soil, and wrap the fruit needles with a black opaque plastic film wrapped with 29 g of special fruit needle culture substrates.

Abstract

The invention discloses a method for promoting overground fruiting of peanut gynophores, which comprises the following steps: preparing a special gynophore culture medium, carrying out bandage treatment on overground gynophores with a black lighttight plastic film, and carrying out non-isolated culture on the gynophores, wherein the special gynophore culture medium is prepared by evenly mixing white lime, a gelatinizer and a seedling raising substrate in a mass ratio of 1:(5-380):(25-1520). The method mainly solves the problem that the overground gynophores of peanuts can not penetrate into soil to develop into full pods, enhances the propagation coefficients of peanut hybrid F1 and rare seed resources, and can solve the problem that the interspecific cross subsequent generation can not form pods since the plant grows vigorously and the gynophores are too far away from the ground.

Description

technical field [0001] The invention relates to the technical field of peanut breeding and cultivation, in particular to a method for promoting aboveground fruiting of peanut needles. Background technique [0002] Peanut is a self-pollinated plant that blooms on the ground and bears fruit underground. The ovary stalk can be formed 3 to 6 days after the embryo of peanut is fertilized. The ovary stalk and the ovary at its tip are collectively called fruit needles. The characteristics of growing towards the ground, the fruit needles are buried in the soil for 4 to 6 days, and the ovary is expanded horizontally in the soil and develops into pods. Under natural conditions, the pods of the same plant have great differences in maturity due to their different insertion positions. Usually, the needles with higher insertion positions cannot enter the soil in time because of their distance from the ground, and eventually fail to develop. To mature pods, some fruit needles cannot be ef...
