Abstract

The present invention discloses a high-yield cultivation method for calla. The method comprises the following steps: cultivation beds are built in a plastic greenhouse with a steel frame, the width of the cultivation beds is from 1m to 1.5m, the length is from 20m to 40m, and the depth is from 30cm to 50cm; an irrigation channel is built between the two beds, the width of the irrigation channel is from 30cm to 50cm, and the depth is from 30cm to 50cm; the depth of water in the irrigation channel is maintained to reach 15cm to 35cm, and the pH value of the water is from 6.5 to 7; then, composite organic fertilizer comprising 8 portions of nitrogen, 8 portions of phosphorus and 8 portions of potassium is applied in the cultivation beds as base fertilizer, calla seed bulbs are cultivated, relative humidity in the greenhouse is maintained from 80% to 90% all the year around, and conventional management is subsequently carried out. Compared with the prior art, the present invention enables calla to come into flower all the year around, and improves yield by one time. The cultivation method is also simple and practical, and has low cost. The method can be used for the mass cultivation of the calla, and has the effect of improving calla yields in a large range.

Description

The high-yield cultivating method of common calla

Technical field

The present invention relates to a kind of plant cultivation method, particularly a kind of flower cultivation method.

Background technology

The flowering bulb of water chestnut Nelumbo Araeceae, the common calla blade is emerald green, and petal is pure white very large, and just like water chestnut, shape is peculiar, is a kind of important cut-flower flowers, and purposes is very extensive.But the natural florescence of common calla is June in November to next year, only 6-7 month florescence.Bloom the whole year if brought up to the flowering stage of common calla, then not only can reach the effect that improves its plantation output, can also remedy the shortcoming that part can not be viewed and admired common calla period.But the cultivation method that common calla can annual be bloomed yet there are no report.

Summary of the invention

The inventor by testing repeatedly, contrast, study and summing up, has developed a kind of easy to implement and common calla high-yield cultivating method that cost is low on the basis of further investigation common calla ecological characteristics and biological property, finished the invention.

The high-yield cultivating method that the purpose of this invention is to provide a kind of common calla, it not only can make the florescence of common calla long, output is high, and simple, cost is low.

The present invention realizes like this.The high-yield cultivating method of common calla is characterized in that: cultivate by following step;

A, in the steelframe plastic tunnel, build cultivating bed, the wide 1-1.5 rice of furrow, long 20-40 rice, high 30-50 centimetre;

B, between two furrow, repair irrigation canal, width of the channel 30-50 centimetre, dark 30-50 centimetre, keep in the irrigation canal depth of water to reach 15-35 centimetre, water pH value at 6.5-7;

C, execute nitrogen to cultivating bed: phosphorus: the compoiste fertilizer of potassium=8: 8: 8 is cultivated common calla kind ball then as base fertilizer, keeps that annual relative moisture is at 80-90% in the booth, and the common calla cultivation requires to manage routinely.

Compared with prior art, the present invention can make not only that common calla blooms the whole year, output doubles, and cultivation method is simple, cost is low.The present invention can be used for reaching the effect that improves common calla output on a large scale in the large-scale common calla cultivation.

Embodiment

Embodiment.Carry out the cultivation of common calla by following step:

A, build cultivating bed in the steelframe plastic tunnel, furrow are wide 1.5 meters, long 30 meters, high 40 centimetres;

B, between two furrow, repair irrigation canal, 40 centimetres of width of the channels, dark 40 centimetres, keep in the irrigation canal depth of water at 20-30 centimetre, water pH value at 6.5-7;

C, execute nitrogen to cultivating bed: phosphorus: the compoiste fertilizer of potassium=8: 8: 8 is cultivated common calla kind ball then as base fertilizer.Keep the interior annual relative moisture of booth at 80-90%, the common calla cultivation requires to manage routinely.
