Description

The culture technique of precocious flower lotus root

Technical field

The present invention relates to the culture technique of a kind of lotus root, specifically is the culture technique of a kind of precocious flower lotus root.

Background technology

The flower lotus root is sweet and crisp, and can eat raw also and can cook, and medical value is quite high, its Gen Genyeye, the stamen or pistil fruit is precious invariably, all can nourish and be used as medicine.Process powder with lotus root, the antidiarrheal that can help digestion, the appetizing heat-clearing, nourishing is nourished one's nature, and the prevention internal haemorrhage is the first-class supping of the virgin old woman of women and children, valetudinarian and nourish good treasure, welcome by the masses in China various places.Generally in lotus pool, grow at present, the output of colored lotus root is restricted, and seasonality is stronger.

Summary of the invention

The present invention provides the culture technique of a kind of precocious flower lotus root, can spend lotus root in the nonirrigated farmland plantation, and output is high, precocity, quality better.

Technical scheme of the present invention is following: the culture technique of a kind of precocious flower lotus root comprises:

(1) seed selection: should select the healthy and strong kind lotus root of pollution-free, no scab for use, the bud head is excellent.

(2) cultivation skill method

(1), choosing ground, whole ground basal dressing: the lotus root field should select good water-retaining property, up-down water condition good, the clay loam field piece that the content of organic matter is high; In conjunction with the every mu of organic fertilizer 2000-3000 jin of ploughing, 30 jin of composite fertilizers, tilling depth 15-20cm accomplishes that wholely mud rots Tian Ping, fertilizer enough;

(2), plantation: be local best plantation period annual mid-April, at the beginning of booth protection ground cultivation can advance to 4 months; Every mu of field sowing quantity is a 400-500 jin, and seeding row spacing is 0.6-1.2m; During plantation, plant the lotus root bud head oblique cutting dark 10-12cm that buries, the bud head should be parallel with native face, and the back is the joint 2-3cm that bassets; Planting lotus root bud head around the field should be in the field, in case lotus root grows the field piece; Adopt wrong row to intersect in the field and plant, the bud head should not be beneficial to make full use of the field block space only facing one direction;

(3) field management

(1) water layer management: the water layer management principle be shallow-dark-shallow, the initial stage of promptly planting only needs the shoaling layer of 2-3cm, until first upright leaf vegetative period at the beginning of 5 months greatly after January; 7-8 needs the depth of water 15-20cm during month, if storm is arranged, can irritate deep water 50-80ccm in short-term; The growth later stage only needs the shoaling layer of 7-8cm, passes the winter with shallow water;

(2) topdress: topdress altogether vegetative period three times, the first upright leaf phase was promptly executed night soil 2000-3000 jin in the ranks at the beginning of 5 months, urea 10-15 jin, and be at the beginning of 6 months-early July the second time, executes 40 jin in urea for every mu, 60 jin of composite fertilizers, fertilizer can not be executed on leaf; Be day at the beginning of 7 months for the third time, see growing state, can suitably apply fertilizer, as it is relatively poor to grow, then execute urea 10-15 jin for every mu, 40 jin of composite fertilizers, 40 jin of superphosphate, 1000 jin of ash.

(4) gather: gather and look market conditions, generally all can gather later by the end of July.

The invention has the beneficial effects as follows: can spend lotus root in the nonirrigated farmland plantation, and output is high, precocity, quality better; Fill up the market shortage.

Embodiment

(1) seed selection: should select the healthy and strong colored lotus root kind lotus root of pollution-free, no scab for use, the bud head should stand intact.

(2) cultivation skill method

(1) choosing ground, whole ground basal dressing: the lotus root field should select good water-retaining property, up-down water condition good, the clay loam field piece that the content of organic matter is high; In conjunction with the every mu of organic fertilizer 2000-3000 jin of ploughing, 30 jin of composite fertilizers, tilling depth 15-20cm accomplishes that wholely mud rots Tian Ping, fertilizer enough;

(2) plantation: be local best plantation period annual mid-April, at the beginning of booth protection ground cultivation can advance to 4 months; Every mu of field sowing quantity is a 400-500 jin, and seeding row spacing is 0.6-1.2m; During plantation, plant the lotus root bud head oblique cutting dark 10-12cm that buries, the bud head should be parallel with native face, and the back is the joint 2-3cm that bassets; Planting lotus root bud head around the field should be in the field, in case lotus root grows the field piece; Adopt wrong row to intersect in the field and plant, the bud head should not be beneficial to make full use of the field block space only facing one direction;

(3) field management

(1) water layer management: the water layer management principle be shallow-dark-shallow, the initial stage of promptly planting only needs the shoaling layer of 2-3cm, until first upright leaf vegetative period at the beginning of 5 months greatly after January; 7-8 needs the depth of water 15-20cm during month, if storm is arranged, can irritate deep water 50-80ccm in short-term.The shoaling layer that growth only needs 7-8cm the later stage is just passed the winter with shallow water;

(2) topdress: topdress altogether vegetative period three times, the first upright leaf phase was to execute night soil 2000-3000 jin about May 20 in the ranks, urea 10-15 jin, but also green manuring this moment.Be 20-early July of June for the second time, execute 40 jin in urea for every mu, 60 jin of composite fertilizers.At this moment, notice preventing when going to the field that pin from stepping on the lotus root head, fertilizer can not be executed on leaf.Be 15-20 day in July for the third time, see growing state, can suitably apply fertilizer, as it is relatively poor to grow, then execute urea 10-15 jin for every mu, 40 jin of composite fertilizers, 40 jin of superphosphate, 1000 jin of ash.

(3) damage by disease and insect: field lotus root damage by disease and insect is less, only just can find old lotus root Tanaka.

Aphid, prodenia litura, food root leaf beetle are generally arranged, rot, virus disease, brown spot etc.The method of preventing and treating is the same with the field of vegetables control, just needs to add in addition agricultural chemicals adhesive agent (washing powder, washing agent).

(4) gather: gather and look market conditions, generally all can gather later by the end of July.
