Abstract

The invention discloses a chrysanthemum cultivation method. The method is characterized in comprising the steps of (1) land preparation, (2) cultivation trough preparation, (3) cultivation substrate preparation, (4) cultivation substrate laying, (5) field planting and (6) growth period management. According to the invention, native peat soil and bentonite with a volume ratio of 1:1 are added, and organic components are added into the cultivation substrate, such that the soil is loose, rich in humus, and well drained. Cultivated chrysanthemum plants have high disease resistance and rich fragrance.

Description

A kind of breeding method of chrysanthemum

Technical field

The invention belongs to planting technology field, be specifically related to a kind of breeding method of chrysanthemum.

Background technology

Chrysanthemum, perennial catananche, its petal is ligule or tubular.Chrysanthemum is the famous and precious ornamental flower cultivated through long-term artificial selection, also claims skill chrysanthemum, and kind reaches more than 3,000 and plants.Chrysanthemum is China's one of ten large famous flowers, in the cultivation history of state-owned more than 3,000 years, Chinese Chrysanthemum imports Europe into, about late Ming & early Qing.Chrysanthemum is liked in Chinese pole, just chrysanthemum distinguished gathering once one year among the people from the Song dynasty.

Chrysanthemum has certain edibility, just has the chrysanthemum of people's edible fresh as far back as the Warring States Period.Tang and Song Dynasty time, China more has takes fragrant plant and the record making health scentetd.Eat flower in some developed countries now very prevailing, on Beijing of China, Tianjin, Nanjing, Guangzhou, Wuhan and other places, also day by day become fashion.

The cultivation of chrysanthemum adopts culture medium to cultivate more, in prior art, common culture medium is most only considers that lily plant is to the demand of the macroelement such as nitrogen, phosphorus, potassium, and ignore matrix PH, matrix trace element, the PH of irrigation water and the impact etc. of environmental factor, make the way to cultivate of chrysanthemum bad.Because extensive management, the harm of sick worm are seriously at present, flowering rate is low, spend the problems such as of low quality, low in economic efficiency, so invent a kind of breeding method realizing the good way to cultivate of chrysanthemum to seem particularly important.

Summary of the invention

The present invention is in order to realize the good way to cultivate of chrysanthemum, and supplement the matrix trace element agent needed for chrysanthemum, provide a kind of breeding method of chrysanthemum, it is characterized in that, described breeding method comprises the following steps:

(1) wholely: select the soil at underground water pH=7-8, be fully to mix primary turfy soil and bentonite evenly at 1: 1 according to volume ratio, be sprinkled upon in soil;

(2) arrange breeding groove: arrange breeding groove in the place need planting chrysanthemum, the degree of depth of described breeding groove is 19-21cm, and width is 70-74cm;

(3) culture medium processed: cultivate in area soil by every 100m2 and add amino-acid compound fertilizer N15-P15-K17 1.5kg, potassium chloride 1.2kg, urea 1.2kg, nitrate of lime type composite fertilizer N12.2-P0-K0-Ca24.5 1.2kg, EDDHA chelated iron: 0.6kg;

(4) culture medium is laid: the thickness laying culture medium in breeding groove is 16-19cm;

(5) field planting: during plantation, plant is put proper in matrix, planting density 2-4/m2, seeding row spacing 10 × 20cm, planting depth is 2 times of its kind of ball height;

(6) growing season management: control soil moisture content and remain on 55-60%, control relative air humidity is 55-65%, temperature keeps 15-25 DEG C, intensity of illumination controls as 20000lux, stem stalk starts when growing to 10cm to impose amino-acid compound fertilizer by each 10-12kg/667m2,1 time is executed, until before picking flowers 3 weeks every 2 weeks.

Further, the side flower bud above extracing in time according to the growth potential of plant when the 5th bud grows to 0.3-0.5cm, determines 4-5 the bud retained.

The beneficial effect of the invention:

Present invention adds primary turfy soil and bentonite that volume ratio is 1: 1, and in culture medium, add the compositions such as amino-acid compound fertilizer, potassium chloride, urea, nitrate of lime type composite fertilizer, EDDHA chelated iron, make loosing soil, humus enriches, draining is good, guarantee the quality of chrysanthemum, the Dendranthema Growth that the inventive method is cultivated is grown, plant height and healthy and strong, cut-flower rate is high, product are of fine quality, and breeding time is long, and pattern is bright-coloured, blade is vivid, seldom occur that leaf burns, the chrysanthemum plant disease resistance cultivated is strong, aromatic flavour.
