Problems solved by technology

However, all-male breeding of asparagus must obtain asparagus androgenic hermaphrodites and super-male strains, and hermaphrodites are rare in nature, and their development and fruiting are affected by genetic material and environmental factors, and the rate of self-seed setting is low, resulting in breeding It is difficult to obtain materials, and it is greatly restricted by genetic background. The all-male breeding technology is not yet mature, and the varieties of asparagus all-male seeds are rare and the price is high.

Embodiment 1

[0029] In 2016, it was carried out in the experimental base of the Institute of Economic Crops Breeding and Cultivation, Sichuan Academy of Agricultural Sciences. The experimental plot 1, plot 2 and plot 3 were set up, and conventional planting greenhouses were used between the plots, with a spacing of 300-1000m. Asparagus seeds were derived from the commercially available "Atlas" variety.

[0030] The experimental plot 1 was the control group. The specific implementation method adopts the existing conventional cultivation and management method of asparagus, which mainly includes the steps of sowing and raising seedlings, seedbed management, field planting and field management.

[0031] Preparation of plug tray substrate: 32-hole plug tray specifications have a total length of 53.5cm, a total width of 27.5cm, an upper diameter of 6cm, and a height of 5cm. The substrate is mainly made of peat and mixed with natural minerals such as perlite, vermiculite and sawdust.

Embodiment 2

[0052] In this example, the experimental time and place are the same as those in Example 1, and the seeds are from the commercially available "Grande" variety. Two experimental plots 4 and 5 are delineated, and a closed greenhouse is used for barrier isolation between the plots.

[0053] Plot 4 was the control group, which was carried out in greenhouse a.

[0054] The experimental plot 5 adopts the non-all-male variety high-yield cultivation method of the present invention, and the specific implementation method is as follows:

[0055] Preparation of nutrient bowl substrate: The specifications of the nutrient bowl are 8cm in diameter and 8cm in height. The substrate is mainly made of peat and mixed with natural minerals such as perlite, vermiculite, and sawdust.

[0056]Seedling raising and seedling stage management: The method of sowing and raising seedlings is similar to that of Example 1, and single seed is sown in a nutrient pot. In the field management during the seedli...

Abstract

The invention discloses a high-yield cultivation method for non-all-male varieties of asparagus. The high-yield cultivation method has the advantages that the high-yield cultivation method includes steps of sowing common commercially available conventional non-all-male variety seeds of asparagus and raising seedlings, determining sex, carrying out isolation cultivation, carrying out conventional management and the like, and accordingly the purposes of increasing the yield and improving the quality can be achieved.

Description

technical field [0001] The present invention relates to the field of asparagus cultivation, and in particular, to a high-yield cultivation method of non-all-male varieties of asparagus. Background technique [0002] Asparagus (Asparagus officinalis L.) is a perennial herb of the Liliaceae Asparagus genus. It is a kind of high-end nutritious and health-care vegetable that is deeply loved by consumers, and is known as the "King of Vegetables". Through its seed sowing planting, asparagus shoots can be continuously harvested for more than 10 years. [0003] The existing large-scale asparagus planting adopts the seed cultivation method. At present, the best varieties of asparagus on the market are mostly hermaphroditic varieties selected by conventional breeding methods. During the cultivation process, the female and male plants in the population are mixed and distributed, and the theoretical ratio is 1:1. During flowering, female plants in the colony are fertilized and consume...
