Problems solved by technology

However, it has three major physiological defects at the same time: one is that the seedlings have extremely poor resistance to root rot, resulting in a large number of nests; Seedlings lodging: the third is that the plant pods are short
Since the above physiological defects are inherent, it is difficult to overcome them through conventional cultivation techniques.

Embodiment Construction

[0016] Experimental variety: dwarf sword bean from an American supplier, purchased from Liaoning Zhenfeng Seed Industry Co., Ltd.

[0017] Test time: mid-March.

[0018] Carry out conventional seedling cultivation on the sword bean seeds first, when the first pair of true leaves spread out, the seedlings are lifted out in time, and the cotyledon is used as the benchmark to align, 20-30 seedlings in a bunch, tied with a rubber band; Cut off at 5cm below, discard the rhizome and the roots below, and soak the wound within 5 minutes. Sterilize the root-promoting solution for 10 seconds, and dip it to a depth of 5cm; then stand it in the activated carbon powder that has been crushed to 180 mesh and heated to 45°C for 30-40 minutes before planting. The depth of planting is based on the cotyledons just exposed to the ground , Then irrigate with clear water, and then pour with light fertilizer after 3 days. After 7 days, the leaves turn dark green and enter the routine management.

Abstract

A dwarf sword bean is a new product of vegetables emerging in recent years and has the advantages of early time to market, no strings, ageing resistance and easy intercropping with other crops, etc. However, the dwarf sword bean has three physiological defects that: 1, the root rot resistance of seedlings is poor so as to cause great nests without seedlings; 2, the seedlings are extremely slender so as to cause lodging of the seedlings; and 3, the pod bearing period of the plant is short. The invention provides a cultivation method for removing physiological defects of the dwarf sword bean, which comprises the steps of cutting the root of the germinated dwarf sword bean and transplanting, and changing the original taproot system of the seedling into the fibrous root system. Therefore, the hidden danger of root rot is removed, the lodging problem of the seedlings is thoroughly solved, the pod bearing peak time of the dwarf sword bean is prolonged, and the yield is improved by over 30%.

Description

technical field [0001] The invention belongs to the technical field of dwarf sword bean cultivation, and in particular relates to a cultivation method for eliminating physiological defects of the dwarf sword bean by cutting off the root of the germinated dwarf sword bean and then transplanting. Background technique [0002] Sword bean is a vegetable variety that residents in East China prefer to eat. The dwarf sword bean has the advantages of being on the market early, has no gluten, and is resistant to aging. At the same time, because the plant is short, it is conducive to intercropping with other crops. The planting area has continued to expand in recent years. However, it has three major physiological defects at the same time: one is that the seedlings have extremely poor resistance to root rot, resulting in a large number of nests; Seedling lodging: The third is that the plant pod formation period is short. Since the above physiological defects are inherent, it is diffi...
