Method for urging peanut gynophores to fruit on ground

A technology of fruit needles and peanuts, which is applied in the field of promoting peanut fruit needles to bear fruit on the ground. It can solve the problems of great difference in maturity, low fertility of interspecific hybrids, and high conditions, so as to achieve easy operation, meet mechanical stimulation, and increase reproduction coefficient.

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] A method for promoting aboveground fruiting of peanut needles, which is realized by the following steps: preparing a special needle culture substrate, wrapping the aboveground needles with a plastic film, and performing non-isolated culture on the needles; culturing the special needles The substrate is made by mixing calcium superphosphate, gel and seedling cultivation substrate according to the mass ratio of 1:7:27. The gel is made by mixing water-retaining agent and water at a mass ratio of 1:300, and 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 the peanuts are sown, use conventional field management methods for water and fertilizer management and intertillage soil cultivation. During the flowering and needle stage, select fruit n...

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 calcium superphosphate, gel and seedling cultivation substrate according to the ratio of mass ratio 1:40:158; the gel is made of water retaining agent and water according to the mass ratio of 1: 350 ratio mixing made. During the flowering and needle-setting stage, select the 3-4 cm long fruit needles that have not been buried in the soil, and wrap the fruit needles with a black opaque plastic film wrapped with 27g of special fruit needle culture substrate.

Embodiment 3

[0031] The technical scheme that present embodiment 3 adopts is different from embodiment 1:

[0032] The prepared special fruit needle culture substrate is made by mixing calcium superphosphate, gel and seedling cultivation substrate according to the ratio of mass ratio 1:5:20; The ratio of 250 is mixed well. During the flowering and needle-setting stage, select fruit needles 3 to 4 cm long 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 urging peanut gynophores to fruit on the ground. The method comprises the steps of manufacturing special gynophore culture substrates, and utilizing a black light-proof plastic film to perform bandage treatment on the gynophores on the ground; and enabling the special gynophore culture substrates to be formed by evenly mixing calcium superphosphate, gel and seedling culture substrates according to the mass ratio of 1:(4-110):(16-440). The method mainly solves the problem that the upper gynophores of peanuts cannot enter soil to be developed into full legumes, the reproduction coefficient of the peanut hybrid F1 generation and rare germplasm resources is improved, and the problem that interspecific filial generations cannot form the legumes due to the fact that plants grow vigorously and the gynophores are too far away from the ground can also be solved.

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...
