Abstract

The invention discloses a greenhouse cultivation method for cress sprouts, which belongs to the field of vegetable cultivation. In the invention, the cultivation and production for the cress sprouts in a greenhouse during the winter in the North are realized through the steps of preparing a seedbed, planting seedlings, heating a culture substrate, covering the vegetable and harvesting the cress sprouts. In the method, a film is adopted to separate the culture substrate and greenhouse soil, so as to prevent soil-borne diseases in the soil from entering the culture substrate and ensure that thecress sprouts are free from the damage of plant diseases and insect pests; an electric heating wire is adopted to heat the culture substrate, so as to ensure the proper temperature of root growth, the prosperous root system and the rapid growth; and non-woven fabric and substrates are adopted to cover the cress sprouts, so as to ensure the covering matters to have better air permeability and proper volume weight; therefore, the cress sprouts are straight, crispy and white.

Description

A kind of method of greenhouse culture celery bud

Technical field

The invention belongs to the vegetable growing field, be specifically related to a kind of method of greenhouse culture celery bud.

Background technology

The celery bud is the special product bud dish in Lujiang County Bai Hu town, Anhui Province, is on the basis of former oenanthe stolonifera, handles a kind of local characteristic vegetables of cultivating through the soil dry farming.Celery bud look white as a jade, and delicate fragrance is tender and crisp, nutritious, and unique flavor can be used for frying, boiling hot, cold and dressed with sauce etc.Since throwing in market, favored by the consumer, be that a Pan Yingyangfeng is real on the winter-spring season people dining table, clear and melodious savoury dish.According to research, the celery bud contains needed by human body multivitamin and amino acid etc., has functions such as refrigerant analgesic, strong cloudy kidney tonifying, the blood fat that brings high blood pressure down.In addition, anosis worm harm need not be used chemical pesticide and pollution-free in the celery blastogenesis product process, and extremely the consumer welcomes.Therefore, has vast potential for future development.

But; Producing and selling of celery bud at present and edible Anhui, Jiangsu one band of only limiting to; Because its geographical position, weather conditions are adapted at producing in autumn end, winter and early spring the celery bud, vast northern area very not big at the whole nation, particularly greenhouse area, that can produce vegetables winter is promoted.

To top problem, the present invention proposes the method for producing the celery bud in a kind of northern in the winter time greenhouse.

Summary of the invention

The object of the present invention is to provide a kind of method of greenhouse culture celery bud, solve the producing and selling of celery bud and edible geographical limitation problem.

A kind of method of greenhouse culture celery bud is characterized in that, comprises the steps:

(1) planting bed prepares: early September-early October, in the greenhouse, carry out the kind bed of celery bud and prepare.Each plants bedside 2-4 rice, and length is not limit, and elder generation carries out ground smooth, spreads plastic film then on the ground; On plastic film, press the spacing of 20-30cm, get the aperture that diameter is 2-3mm equably; With perlite, the peat composed of rotten mosses and thick river sand 1: 1 by volume: (0.5-1) evenly mix, process matrix, making its unit weight was 0.4-0.6g/cm ³Add the ratio of 7-12 kilogram sterilization chicken manure, 2-3 kilogram phosphorus two ammoniums, 1.2-1.8 kilogram potassium sulphate again according to every cubic metre of matrix, fertilizer and matrix mixing are formed cultivation matrix, be tiled on the plastic film, its thickness is generally 10-15cm; Be the 7-10cm place in the cultivation matrix degree of depth again, lay heating wire;

(2) planting seedlings: with clear water cultivation matrix is irrigated earlier, make its moisture content at 70-85%; Then seedling is cut into the stem section of 17-25 centimeter length, evenly is sprinkled into the seedbed, and makes it non-overlapping copies; Later on cultivation matrix is often watered clear water, keep bed planting matrix to be in moisture state all the time, moisture content is at 50-75%;

(3) cultivation matrix is heated: when the cultivation matrix temperature is lower than 18 ℃, with heating wire cultivation matrix is heated, make its temperature be not less than 18 ℃ all the time;

(4) after leaf mustard: planting seedlings 60-80 days; Long when the axillalry bud of seedling eustipes part to more than 10-15 centimetre, when having 10 multi-disc true leaves, on the seedbed, make celery swing to same direction; With nonwoven celery is covered earlier, cladding thickness is 10-17 centimetre a matrix on nonwoven again;

(5) gather: after leaf mustard 25-30 days, can carry out gathering of celery bud.

Beneficial effect of the present invention: 1, among the present invention, cultivation matrix and greenhouse soil are separated, avoided the soil-borne disease in the soil to get into cultivation matrix, guaranteed that the celery bud does not receive the harm of damage by disease and insect with film.What 2, cultivation matrix adopted is artificial mixed matrix, but not natural soil.Cultivation matrix not only has unit weight, porosity, gas permeability and water binding capacity preferably, and the fertilizer of being sneaked into is comprehensive, balanced.Like this, the seedling that cultivates is healthy and strong, nutritious.3, adopt heating wire that matrix is heated, guaranteed the preference temperature of root growth, well developed root system, growth are rapidly.4, adopt nonwoven and matrix that the celery bud is covered, guaranteed that covering had both had gas permeability preferably, suitable unit weight is arranged again, make the celery bud straight, crisp white.

Embodiment

With specific embodiment the present invention is further specified below:

Embodiment 1

In special vegetable base, Xiao Tang mountain, ChangPing, Beijing City district, the method instance that carries out celery blastogenesis product is following:

(1) planting bed prepares: September 30, the kind bed of in greenhouse by solar heat, selecting suitable place to carry out the celery bud is prepared, and each plants 3 meters of bedsides, 6.5 meters of length (the span direction along north and south, greenhouse).Elder generation carries out ground smooth, spreads plastic film then on the ground.On the plastic film, press the spacing of 25cm, get the aperture that diameter is 3mm equably.With perlite: the peat composed of rotten mosses: thick river sand evenly mixed in 1: 1: 0.8 by volume, processed matrix; Ratio according to every cubic metre of matrix is added 12 kilograms of sterilization chicken manures, 3 kilograms of phosphorus two ammoniums, 1.5 kilograms of potassium sulphates forms cultivation matrix with fertilizer and matrix mixing, is tiled on the plastic film, and thickness is 14cm; In the cultivation matrix degree of depth is the 8cm place, lays electric heating wire, realizes heating to cultivation matrix.

(2) planting seedlings: before the field planting, with clear water cultivation matrix is irrigated earlier, make its moisture content about 80%; Then seedling (old celery) is cut into stem section long about 22 centimetres, evenly is sprinkled into the seedbed, and makes it non-overlapping copies; Later on cultivation matrix is often watered clear water, keep bed planting matrix to be in moisture state all the time, moisture content is about 65%.Owing to mixed chicken manure and chemical fertilizer in the cultivation matrix, seedling just can ramp under the greenhouse advantage of liquid manure abundance.

(3) cultivation matrix is heated: when the cultivation matrix temperature is lower than 18 ℃, by heating wire cultivation matrix is heated, make its temperature be not less than 18 ℃ all the time.The realization of this part function leans on the heating wire heating system to accomplish automatically, because there is temperature sensor to be embedded in the measurement of carrying out substrate temperature in the matrix.Suitable cultivation matrix temperature helps the g and D of seedling root system, promotes the quick growth of seedling.

(4) leaf mustard: planting seedlings is after 75 days, about the axillalry bud length to 12 of seedling eustipes part centimetre, have 12-13 sheet true leaf, begins to carry out leaf mustard.On the seedbed, make celery swing to same direction, celery is covered earlier with nonwoven, cladding thickness is 15 centimetres a matrix on nonwoven again.

(5) gather: leaf mustard carried out gathering of celery bud after 30 days.
