Embodiment 1
[0031] (1) Cultivate the mother plant, and the fertilization level is as usual.
[0032] (2) Selection of radish cuttings:
[0033] Radish has strong branching ability, which is conducive to the selection of cutting branches. Bolting-resistant white radish in spring enters the reproductive growth period 15 days after the bolting stage, select a 20-30cm long, 0.5-1cm thick stem, healthy and disease-free first-level side branches with 3-6 leaves as cutting side branches; Cuttings are classified according to specifications to facilitate uniform growth, and seeds are harvested in batches.
[0034] (3) Base incision:
[0035] After the side branches are selected, gently cut them off from the base with a sharp blade. The incision should be smooth and horseshoe-shaped to facilitate wound healing. The angle of the cut surface is 30 degrees. The time to cut side branches can be carried out before 10:00 in the morning, after 15:00 in the afternoon or on cloudy days.

Abstract
The invention discloses a spring bolting-resistant white radish side branch cutting seed multiplication method. The method includes the steps: firstly, selecting a primary side branch with 3-6 leaves as a cutting side branch and cutting the side branch from a base by a blade after selecting the side branch; rapidly and shallowly dipping the side branch in rooting agents and then performing cuttage after a cut of the cut side branch naturally heals; performing cutting rooting domestication survival by taking decayed straws, rice husks, vermiculite and decayed cow dung as seedbed matrixes and by regulating temperature, humidity and illumination; taking out and transplanting the side branch when new leaves grow and root development is fine, directly starting reproductive growth after the side branch survives, and harvesting white radishes after seed maturation. Plants cultivated by the method are stable in heritability, robust and high in yield transplanting survival rate, and root systems are developed. By the side branch cutting method, the problem of germplasm loss caused by stock tree rot in the radish seed reserving process is solved, the trouble of performing seed multiplication again in a next year is omitted, and time and expenditure are saved.
Description
technical field [0001] The invention belongs to the technical field of radish seed propagation, and in particular relates to a method for seed propagation of bolting-resistant white radish by side branch cuttings in spring. Background technique [0002] Radish is an important vegetable crop in my country, with a planting area of about 1.2 million hectares, ranking the top three in the planting area of various vegetables, second only to Chinese cabbage and potatoes. With the development of agricultural production and the improvement of living standards, more types of radish varieties are needed to meet the needs of year-round balanced supply of radishes and the needs of different tastes. On the basis of maintaining traditional autumn sowing cultivation, actively developing spring sowing radish production and improving its annual balanced supply level have become the current development direction of radish cultivation. The production of radish for export earning foreign e...
