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 have been 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 the main road vegetables on Guangdong, Guangxi and other places, the ground such as anniversary transportation and sales Hong Kong, Macao becomes 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, cultivation method of the present invention is simple, and it is low to have a cost, and output is high, the advantages such as convenient management.

The present invention adopts following technical scheme:

A kind of cultivation method of the spring vegetable heart is characterized in that comprising following content:

(1) planting environment is selected:

(a) environmental condition: water, light, thermal resource are than 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 sulphate, 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 farmers' cow dung, pig manure, and upper soll layer 10-15 centimetre soil is mixed thoroughly;

(2) seeding and seedling raising: early, the middle cooked food heart is take live as main, beat first the sowing cave, seed enters the cave, mu sowing quantity 0.35-0.45 kilogram, put into Nutrition Soil in every cave, the weight portion of Nutrition Soil material composition constitutes: 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 morning, each trickle of dusk once keep ground moistening, and the rear sunshade net of throwing off rapidly of emerging prevents excessive growth;

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

(4) seedling thinning or transplanting: the time that will reach after the seedling true leaf launches is removed overstocked close stand and weak seedling, and 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;

Drench sufficient normal root water behind the cabbage heart seedling raising and transplanting, keep ground moistening, with rapid recovery growth, after planting above the furrow face about 1 meter cover the black sunshade net, after surviving, remove covering;

In time topdress in conjunction with thinning when (5) seeding stage is to two leaf stage, execute slowly-releasing potassium chloride 2-3 kilogram, calcium dihydrogen phosphate 10-15 kilogram for every mu and mix and use, should note avoiding fertilizer to drop on the bud during fertilising, cause mashed flower bud, morning every day, late each trickle once keep ground moistening; Spray a foliage fertilizer every 1-2 week after the field planting, 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 the cabbage caterpillar occurrence in peak period arrives, spray with killing 32-40 g/acre in diamond-back moth agricultural chemicals, being watered;

(7) gather: when tender flower stalk is opened 1-5 Xiao Hua, height flush with plant leaf or near the time, should in time gather, gather height take about the 25-30cm as standard.

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

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

(2), feldspar in powder was calcined 4-5 hour under 400-450 ℃, feldspar in powder, sodium rice carbon are mixed, add again and be equivalent in the 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 the potassium chloride particle oven dry;

(4), the pyrethroid mixture of can outside particle, spraying again again, then the oven dry, can not spray yet.

Advantage of the present invention:

Cultivation method of the present invention is simple, and it is low to have a cost, and yield is high, and the advantages such as convenient management are fit to extensive cultivation.
