Abstract

The cultivation method of prolonging the growth period of water parsnip in spring and summer includes digging out the stubble root after water parsnip harvest and separating into single plants, transplanting the single plants with root system in other field with applied organic fertilizer, watering or irrigating to moisten soil, applying quick acting nitrogen fertilizer after the new seedlings grow to about 5 cm long, and growing to 20 cm long before harvesting. The present invention makes it possible to fill the market gap of supplying water parsnip product.

Description

A kind of cultivation method that prolongs growth period of water parsnip in spring and summer

Technical field

The present invention relates to a kind of Chinese celery cultivation method, particularly a kind of cultivation method that prolongs growth period of water parsnip in spring and summer.

Background technology

Before the present invention, because of Chinese celery belongs to cooling property vegetable crop, generally in spring autumn and winter the cool seasonal growth and the listing of gathering.Under the conventional cultivation condition, enter season high temperature long-day spring and promptly begin to take out living scape, enter generative growth phase.Simultaneously, because temperature raises, plant growth rate under the Routine Management condition is slower, the fibrillatable of taking out living scape and petiole tissue is obvious, mouthfeel is slightly old, can't bear ediblely, therefore, produce at present to go up and wetly plant the Chinese celery outdoor cropping and only gather once in 3～April of spring, gather and finish promptly to plough other crops of back plantation, or stay part growth seedling.Therefore, before the Chinese celery that utilizes the sunshade net to cover ealy maturing culture in July is gathered and goes on the market, occur the Chinese celery supply neutral gear phase of two wheat harvesting periods on the market, can't satisfy the market comsupton needs.

Summary of the invention

Purpose of the present invention just is to overcome above-mentioned defective, invents a kind of Chinese celery cultivation method that can fill up this neutral gear phase.

Technical scheme of the present invention is:

A kind of cultivation method that prolongs growth period of water parsnip in spring and summer, its major technique step is:

(1) at Yangtze river basin spring and summer by the end of April, behind the Chinese celery of gathering at the beginning of 5 months, dig out plant retained root stubble, is divided into individual plant;

(2) individual plant that will leave root system is transplanted other field, transplants spacing 6-8cm;

The field in addition of (3) transplanting applies the fertilizer that becomes thoroughly decomposed with every mu of 1000kg consumption in advance;

(4) water after transplanting or irrigate, make field soil fully moistening;

(5) treat sprouting of lateral bud after, when new talent grows to the 5cm left and right sides, use carbonic hydroammonium available N fertilizer with every mu of 25kg consumption;

(6) when new talent length is above to 20cm, the listing of can gathering.

Advantage of the present invention and effect are to have overcome this Chinese celery supply neutral gear phase, adopt extremely simple cultivation method, its Biological Principles is to improve the rejuvenation ability of plant by measures such as plant division, transplantings, add using of available N fertilizer, keep and strengthen plant and carry out nourishing and growing faster, suppress the increase that it enters crude fiber content in generative growth phase and the product organ, thereby continue to form the tender product supply the market of children.Under the weather conditions of the Yangtze river basin, can make wet plant Chinese celery tailend of gathering in spring by by the end of April, at the beginning of 5 months, be deferred at the beginning of late May and even 6 months, obviously prolonged the listing supply phase of Chinese celery, further enrich market.Per mu yield can reach more than the 1000kg, and economic benefit and social benefit are all more remarkable.

Embodiment

Under the weather conditions of the Yangtze river basin, for the launch supply phase is further postponed, and guarantee that sprouting of lateral bud has enough nutrients, and select the plant that the later stage gathers for use, its residual stem is thick, it is more to reserve nutrient, therefore, after should gathering by the end of April, at the beginning of 5 months, dig out plant retained root stubble, be divided into individual plant, select the root stubble of thick (more than the 1.5cm) of residual stem, the individual plant field transplanting in addition again of root system will be arranged; Transplant field applies the fertilizer that becomes thoroughly decomposed with every mu of 1000kg consumption, as pig manure, cow dung etc.; Transplant spacing between 6-8cm, water after planting or irrigate, make field soil fully moistening or very thin water layer arranged. find through overtesting, also can germinate lateral bud and growth on the plant root stubble that does not have to transplant, from the vanelets form, lateral bud is taken out living newborn plant and is also belonged to and nourish and grow, but its growing way is weak, growth rate is starkly lower than to transplant and handles; Processing is strong with the new talent growing way that its lateral bud of processing that is divided into individual plant germinates, growth rate is the fastest and transplant, illustrate that transplanting and plant division have obviously improved the rejuvenation ability, newborn plant growing way strengthens, correspondingly suppressed the transformation of plant to the reproductive growth direction. after treating sprouting of lateral bud, general every each individual plant is sprouted 3-5 new talent, when new talent length arrives the 5cm left and right sides, use carbonic hydroammonium or quite contain the available N fertilizer that N measures with every mu of 25kg consumption, impel new talent to nourish and grow apace, further suppress the transformation of plant to the reproductive growth direction; When new talent length is above to 20cm, the listing of can gathering.

According to the climate difference in various places or each time, general harvesting standard is when nipping off newborn plant base portion with hand, and plant is fractureed easily; If the plant base portion is difficult for being fractureed, then explanation will be gathered as early as possible, otherwise the product mouthfeel can obvious ageing, fibrillatable is obvious, the consumer generally is difficult for accepting.

Claims (2)

1. a cultivation method that prolongs growth period of water parsnip in spring and summer the steps include:

(1) at Yangtze river basin spring and summer by the end of April, behind the Chinese celery of gathering at the beginning of 5 months, dig out plant retained root stubble, is divided into individual plant;

(2) individual plant that will leave root system is transplanted other field, transplants spacing 6-8cm;

The field in addition of (3) transplanting applies the fertilizer that becomes thoroughly decomposed with every mu of 1000kg consumption in advance;

(4) water after transplanting or irrigate, make field soil fully moistening;

(5) treat sprouting of lateral bud after, when new talent grows to the 5cm left and right sides, use carbonic hydroammonium available N fertilizer with every mu of 25kg consumption;

(6) when new talent length is above to 20cm, the listing of can gathering.

2. a kind of cultivation method that prolongs growth period of water parsnip in spring and summer according to claim 1, the fertilizer that it is characterized in that becoming thoroughly decomposed is the animal wastes of becoming thoroughly decomposed.
