Abstract
The invention discloses a method for improving yield of cabbage mustard seed production. The method specifically comprises the following steps of sowing and seedling in a tray, and planting in a crop field when the seedling grows with four leaves and one core; when the height of the plant is 30cm, cutting 5cm from the top end of a main stem of the cabbage mustard by a sickle; remaining four most robust primary branches, and cutting the excessive primary branches at the bottom parts of the branches by a shear; when the length of each primary branch is 30cm, cutting 5cm from the top end of each branch by the shear; after the top part of each primary branch is cut off, and when the length of a secondary branch is 5cm, remaining four most robust secondary branches at each primary branch, and cutting the excessive secondary branches at the bottom parts of the branches by the shear. The cabbage mustard treated by the method has the advantages that the number of bolting and flowering is greatly increased, the yield of seed production is equal to about 2.5 times of the yield of normal seed production, the flowering period is centralized, the maturing period of the seeds is uniform, and the harvesting of the seeds is easy. The method has the advantages that the method is simple, the implementing is easy, the yield is greatly increased in large-area cabbage mustard seed production, the time and labor in harvesting of the seeds are saved, and the popularizing value is realized.
Description
Technical field
The present invention relates to a kind of method increasing substantially cabbage mustard hybrid seed yield, belong to field of plant growing technology.
Background technology
Cabbage mustard, has another name called: spend cabbage mustard, greenery wild cabbage, cabbage mustard, mustard, leaf mustard in vain, and be Cruciferae, Brassicas annual herb plant, cultivation history is long, is one of special vegetable of China.The tender flower stalk of cabbage mustard is tender, fresh and crisp, fresh and sweet, delicious, colored a kind of sedge tender with fertilizer and tender leaf edible, the fresh tender flower stalk moisture content of every 100 grams of cabbage mustard 92 ~ 93 grams, vitamin C 51.3 ~ 68.8 milligrams, also has considerable mineral matter, be cole vegetables Middle nutrition than more rich a kind of vegetables, can to stir-fry and eat, soup food, or to garnish food.Cabbage mustard containing cellulose, carbohydrate etc.Its taste is sweet, and property is pungent, possess sharp aquation phlegm, removing toxic substances dispel the wind, except heat symptoms caused by an exopathgen, separate tired, clear away heart-fire the effects such as improving eyesight, very popular.
There are the provinces and regions such as Guangdong, Guangxi, Fujian and Taiwan cabbage mustard main producing region, and there is a small amount of cultivation coastal and northern Suburb Areas of Big Cities.Also there is the cultivation of larger area in this year on the ground such as Sichuan, Yunnan, and seed demand increases year by year.Cabbage mustard, in production of hybrid seeds process, is easily subject to cabbage caterpillar and diamond-back moth is caused harm, and late growth stage is subject to again the impact of high temperature, causes seed production significantly to reduce.
Existing cabbage mustard production kind is all crossbreed, and crossbreed growth potential, resistance are all better than conventional kind.Cabbage mustard is because terminal inflorescence is few, and side shoot is few, belongs to the kind that hybrid seed yield is on the low side in cole vegetables, therefore finds a kind of method tool improving its production of hybrid seeds amount to be of great significance.
Summary of the invention
For present situation, the invention provides a kind of method improving cabbage mustard hybrid seed yield, the method is easy to operation, can effectively improve cabbage mustard hybrid seed yield.
To achieve these goals, the invention provides following technical scheme:
Improve a method for cabbage mustard hybrid seed yield, comprise the following steps:
(1) adopt cave dish seeding and seedling raising, seedling 4 leaf wholeheartedly time field planting land for growing field crops;
(2) with reaping hook, cabbage mustard stem top is sliced off 5cm during plant height 30cm;
(3) after stem top slices off, stay the one-level branch that 4 the most sturdy, unnecessary one-level branch scissors is cut bottom branch;
(4), when one-level long branch is long to 30cm, with scissors, 5cm is cut on each branch top;
(5), after one-level branch is pinched, each one-level branch can be emerged second branch, wait second branch grow to 5cm long time, each one-level branch stays 4 second branch the most sturdy, all the other second branch scissors are cut bottom branch;
(6) after, normal rich water quality management, cuts off whole strain plant until disposable during seed maturity, results seed.
In the method for aforementioned raising cabbage mustard hybrid seed yield, the resident time described in step (1) is after planting about 25 days.
In the method for aforementioned raising cabbage mustard hybrid seed yield, the time that step (2) described cabbage mustard stem top slices off is after field planting about 25 days.
In the method for aforementioned raising cabbage mustard hybrid seed yield, 4 described in step (3) one-level branches the most sturdy are at the different directions of major branch.
In the method for aforementioned raising cabbage mustard hybrid seed yield, described in step (4) is after field planting about 60 days by the time that each branch top is cut.
In the method for aforementioned raising cabbage mustard hybrid seed yield, the secondary branch described in step (5) grow to 5cm long time time be that one-level branch is pinched latter about 10 days.
In the method for aforementioned raising cabbage mustard hybrid seed yield, seed maturity described in step (6) refer to kind of pod yellow maturity and seed more than 80% blackening time, select that fine day dew in the morning is not dry frontly disposablely cuts off whole strain plant, after-ripening 4 ~ 5 days, then threshing is also dried to water content below 8% in time.
In the method for aforementioned raising cabbage mustard hybrid seed yield, after removing one-level branch and second branch, smear wound healing agent for plants in incision.
In the method for aforementioned raising cabbage mustard hybrid seed yield, the smearing method of described wound healing agent for plants is: first by wound healing dilution agent 50 times, then the Wound-healing agent after dilution is dipped with hairbrush, uniform application plants wound, wound is covered completely, every 1 gram of Wound-healing agent brushing otch 10-16.
Described wound healing agent for plants is bought from market.
Beneficial effect of the present invention:
Adopt the cabbage mustard plant of process of the present invention, bolting, quantity of blooming increase greatly, and hybrid seed yield is about 2.5 times of normal hybrid seed yield, and the florescence is concentrated, seed maturity is comparatively consistent, and seed is easy to results, disposablely when only needing to wait seed maturity cuts off whole strain plant.And the normal cabbage mustard production of hybrid seeds is because stem is bloomed comparatively early, stem seed maturity is also early many compared with side shoot, and stem seed need gather in advance, could gather in side shoot and bear seeds after stem seed harvesting two weeks.
The inventive method is simple, particularly can increase considerably output when the production of hybrid seeds of large area cabbage mustard, and save time on seed harvest, laborsaving.Can determine thus, the present invention has promotional value aborning.
