Description

A kind of cultivation method of the spring vegetable heart

Technical field

The present invention relates to a kind of cultivation method of the spring vegetable heart, belong to the culture technique field of vegetables.

Background technology

Cabbage heart originates from SOUTHERN CHINA, through long-term selection and cultivation domestication by the easy bolting material of Chinese cabbage, and different types and kind are formed, mainly be distributed in the ground such as Guangdong, Guangxi, Taiwan, Hong Kong, Macao, the Japanese successful introduction of 20th century posterior lobe, cabbage heart is the special product vegetables of Chinese Guangdong, quality is tender, local flavor is good to eat, and energy annually cultivating, so be main road vegetables on the ground such as Guangdong, Guangxi, the ground such as anniversary transportation and sales Hong Kong, Macao, become the vegetables of outlet, also have a small amount of America and Europe that finds a good sale in, be considered as famous and precious vegetables.

Summary of the invention

For better large batch of growing and cultivation cabbage heart, the object of the present invention is to provide a kind of cultivation method of the spring vegetable heart, the advantage such as cultivation method of the present invention is simple, has cost low, and output is high, convenient management.

The present invention adopts following technical scheme:

A cultivation method for the spring vegetable heart, is characterized in that comprising following content:

(1) planting environment is selected:

(a) environmental condition: water, light, thermal resource are compared with horn of plenty, away from pollution source;

(b) soil condition: soil plough horizon is deep, physical features is smooth, irrigation and drainage are convenient, soil structure is suitable, fertilizer, 8-10 kilogram urea, 2-3 kilogram potassium sulfate, 50-80 kilogram bamboo charcoal, 20-30 kilogram Iron-ore Slag, the 2-3 kilogram quicklimes such as every mu of soil application 1000-1500 kilogram of farmers''s cow dung, pig manure, and the soil of upper soll layer 10-15 centimetre is mixed thoroughly;

(2) seeding and seedling raising: early, the middle cooked food heart is take live as main, first beat sowing cave, seed enters cave, mu sowing quantity 0.35-0.45 kilogram, in every cave, put into Nutrition Soil, the weight portion of Nutrition Soil material composition is configured to: paulownia sawdust 1-2, humus 1-2, weathered coal 2-3, rural area soil 10-12, sepiolite 1-2, broadcast rear with the covering of black sunshade net, moisturizing and preventing rain wash and burning sun tan by the sun, drench sufficient germination water, fine day early, each trickle once, keeps ground moistening at dusk, throws off rapidly sunshade net and prevent excessive growth after emerging;

(3) crops for rotation arrangement: annual two batches of cabbage heart, sow in early March for first batch, sow mid-June, within after planting 40-45 days, can gather for second batch;

(4) seedling thinning or transplanting: want after seedling true leaf launches and the time is removed overstocked close stand and weak seedling, generally in precontract seedling thinning 1-3 time of buddingging, early, the specification of middle cooked food heart final singling is 11-15cm, the specification of late-maturing cabbage heart final singling is 16-17cm;

After cabbage heart seedling raising and transplanting, drench sufficient normal root water, keep ground moistening, to recover rapidly growth, after cultivation, above furrow face, approximately 1 meter of covers black sunshade net, after surviving, removes covering;

(5) when the seeding stage is to two leaf stage, topdress in time in conjunction with thinning, every mu execute 2-3 kilogram, slowly-releasing potassium chloride, a calcium dihydrogen phosphate 10-15 kilogram mixing is used, and should note avoiding fertilizer to drop on bud when fertilising, causes rotten flower bud, morning every day, late each trickle once, keep ground moistening; After field planting, spray a foliage fertilizer every 1-2 week, foliage fertilizer is converted 500-800 times of water and is sprayed, and foliage fertilizer is mixed by the raw material of following weight portion: ferrous sulfate 2-3, borax 0.5-1.0, ammonium molybdate 0.2-0.3, brassinosteroid 0.002-0.003, methyl α-naphthyl acetate 0.001-0.002;

(6) extermination of disease and insect pest: before cabbage caterpillar occurrence in peak period arrives, with killing diamond-back moth agricultural chemicals 32-40 gram/acre, be watered and spray;

(7) gather: when tender flower stalk is opened 1-5 little Hua, when height flushes or approaches with plant leaf, should gather in time, the height of gathering is take 25-30cm left and right as standard.

2, the cultivation method of the spring vegetable heart according to claim 1, the slowly-releasing potassium chloride described in it is characterized in that is prepared by the following method:

(1), take sodium rice carbon and feldspar in powder, the part by weight of the two is 0.1:1-2;

(2), feldspar in powder is calcined to 4-5 hour at 400-450 ℃, feldspar in powder, sodium rice carbon are mixed, add again and be equivalent in feldspar in powder weight 4-5 water doubly, add the liquefied petrolatum, the paregal O of 1-2%, the wintergreen of 4-5%, the carboxymethyl cellulose of 3-4%, the 3-5% aluminium hydroxide that are equivalent to feldspar in powder weight 2-3%, high speed 1200-1500 rev/min of stirring, obtains dispersion liquid;

(3), dispersion liquid is sprayed at outside potassium chloride particle to oven dry;

(4), can be again at the particle pyrethroid mixture of spraying again outward, then dry, also can not spray.

Advantage of the present invention:

The advantages such as cultivation method of the present invention is simple, has cost low, and yield is high, convenient management, are applicable to extensive cultivation.
