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

[0037] In 2016, it was carried out at the experimental base of the Economic Crop Breeding and Cultivation Research Institute of the Sichuan Academy of Agricultural Sciences. Experimental plots 1, 2 and 3 were set up, and conventional planting greenhouses were used between each plot, with a spacing of 300-1000m. Asparagus seeds were obtained from the commercially available 'Atlas' variety.

[0038] Experimental plot 1 was the control group. The specific implementation method adopts the existing asparagus conventional cultivation and management method, which mainly includes the steps of sowing and raising seedlings, seedbed management, planting and field management.

[0039] Preparation of tray matrix: 32-hole tray specifications with a total length of 53.5cm, a total width of 27.5cm, an upper diameter of 6cm, and a height of 5cm. The matrix is ​​mainly made of peat, mixed with natural minerals such as perlite, vermiculite, and sawdust.

[0040] Sowing and raising seedlings: w...

Embodiment 2

[0060] In this example, the experiment time and place are the same as those in Example 1, and the seeds are from the commercially available "Grand" variety. Delineate two experimental plots 4 and 5, and use a closed greenhouse for barrier isolation between the plots.

[0061] Plot 4 is the control group, which is carried out in greenhouse a.

[0062] Experimental plot 5 adopts the non-all-male variety high-yield cultivation method among the present invention, and concrete implementation method is as follows:

[0063] Preparation of the nutrition bowl substrate: The nutrition bowl specification is 8cm in diameter and 8cm in height.

[0064] Seedling raising and seedling stage management: the seedling raising method is similar to that of Example 1, and a single seed is sown in a nutrient bowl. Field management at the seedling stage should pay attention to this method, which needs to wait for the seedlings to bloom before transplanting, so the time for asparagus seedlings on the ...

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 invention relates to the field of asparagus cultivation, and in particular, relates to a high-yield cultivation method for non-all-male varieties of asparagus. Background technique [0002] Asparagus (Asparagus officinalis L.) belongs to the perennial herbaceous plant of the genus Asparagus in the family Liliaceae. It is a high-grade vegetable that is loved by consumers for nutrition and health care, and is known as the "king of vegetables". Planted by its seed sowing, young asparagus stalks can be harvested continuously for more than 10 years. [0003] The existing large-scale asparagus plantation all adopts the seed cultivation method. At present, commercially available asparagus varieties are mostly hermaphroditic varieties selected by conventional breeding methods. During the cultivation process, female plants and male plants are mixed in a population, and the theoretical ratio is 1:1. During the flowering stage, the female plants in the colo...
