Embodiment Construction

[0027] The following are specific embodiments of the present invention to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0028] A cultivation method for improving the yield and seed production purity of mustard tuber, which includes the following steps:

[0029] Step 1. Collection, processing and storage of mustard seeds: collect large, middle and small mustard seeds for sowing;

[0030] Step 2. Choose suitable land for planting; choose an area with good isolation conditions, sufficient sunlight, convenient drainage and irrigation, and less rain during bolting and flowering period;

[0031] Step 3. Planting for large plants to retain seeds: The planting period is from October 3 to October 8, 12,000 to 14,000 plants per mu;

[0032] Step 4. Planting for the middle plant to retain seeds: The planting period is late October, with 18,000 to 20,000 plants per mu;

[0033] Step 5: Planting of small plants: the...

Abstract

The invention discloses a breeding method for improving yield and seed production purity of hot pickled mustard tubers. According to the method, big-plant reserved seeds, medium-plant reserved seeds and small-plant reserved seeds of the hot pickled mustard tubers are respectively seeded in different periods; planting of plants, fertilization, seed selection, pruning and harvesting are performed on big, medium and small hot pickled mustard tuber plants by adopting different treatment means; and the seeds of the hot pickled mustard tubers are produced by adopting a repeated reproduction technical route of reproducing big-plant reserved seeds with the big-plant reserved seeds, reproducing medium-plant reserved seeds with the medium-plant reserved seeds and reproducing production seeds with the small-plant reserved seeds. The method has the advantages of greatly improving the yield and the purity of the hot pickled mustard tuber seeds and reducing the cost and the risk of seed production.

Description

Technical field [0001] The invention relates to the technical field of mustard tuber cultivation, in particular to a cultivation method for improving the yield and seed production purity of tuber mustard. Background technique [0002] Mustard is a mustard vegetable with swollen tuberous stem as the product organ. It is suitable for fresh sale and processing. The main cultivation areas are Zhejiang, Chongqing, Sichuan and other provinces and cities. A large number of studies have proved that mustard tuber is a kind of vegetable with strict product organ requirements. Compared with other vegetable crops, seed production is more difficult and varieties are prone to degradation. During the production of mustard seeds, due to mixed biology, careless selection or improper selection, improper seed collection methods and technical routes, the variety of mustard varieties is degraded, which is manifested as a decrease in uniformity, a decrease in yield, an increase in hollowness, and chan...
