Abstract

The invention discloses a method for cultivating asparagus seedlings in nutrition plates in the early state. The method includes the steps that first, seeds are dried in the sun, and the seeds are placed in the sun and exposed in the sun for six hours to eight hours; second, the seeds are soaked after being dried in the sun, and the seeds are placed in 30 DEG C water containing carbendazim to be soaked for 48 hours to 72 hours; third, seedlings are cultivated in the nutrition plates, the seeds are sown in the nutrition plates in which substrates are contained, germinated seedlings are cultivated, the seedlings are transplanted into the field after two months, and conventional field management is performed. With the method, the germination acceleration step commonly used in current asparagus cultivation is omitted, the seeds are directly sown in the nutrition plates to be cultivated, then conventional field management is performed, the steps are simple, a large amount of manpower and material resources are saved, disease and pesticide damage is small in the asparagus growing process, and the yield is increased.

Description

A kind of method that asparagus early nutrition dish is grown seedlings

Technical field

The present invention relates to a kind of cultivation of asparagus method, a kind of method that particularly asparagus early nutrition dish is grown seedlings.

Background technology

Asparagus is a kind of famous and precious health-care vegetable, and its tender stem local flavor deliciousness is delicate good to eat, has very high edible and medical value, is one of the world's ten large famous dishes, has the title of " kings of vegetables ", the states such as fashionable Europe, America, Korea S, Japan.Asparagus is the herbaceous plant of perennial root, and the tender shoots that spring, autumn extract out is edible " asparagus ".Asparagus is a kind of famous and precious traditional Chinese medicine, and ancient times, Shennong's Herbal claimed that it is " on top grade ", and Compendium of Material Medica claims it " to separate the poison of all knurls ".Show according to scientific research, asparagus is rich in 17 seed amino acids of tissue protein and needed by human body, wherein particularly abundant with the amino acid content of asparagus, in addition, particularly abundant with vitamin A content in contained vitamin, various trace elements is comparatively outstanding with the content of selenium, and all these materials all have effect that inhibition cancer cell produces.

Due to asparagus seeds seed coat keratin, water penetration is poor, and water suction is slow, and seed dormant deep mixed, occurs at low temperatures bud is slow, and the seeding stage is long, germinates, emerges for accelerating it, often adopts prior to seeding the method for vernalization at present; With the water seed soaking of 26-29 DEG C 3.5 d, drain and mix with dry sand or fine earth on a small quantity, be placed on moisturizing vernalization at 20-25 DEG C of temperature, use clear water drip washing 1-2 time every day, this method is higher to temperature in vernalization process, humidity requirement, expends a large amount of human and material resources and bud ratio lower, affects Yield of Asparagus.

Summary of the invention

For the problems referred to above that exist in current asparagus cultivation, a kind of method that provides asparagus early nutrition dish to grow seedlings, simplifies vernalization step, improves Yield of Asparagus, and the present invention is achieved in that

The method that asparagus early nutrition dish is grown seedlings, step is as follows:

(1) bask seeds before sowing, temperature is at 25 DEG C---30 DEG C time, seed is placed in to the straight 6h---8h of solarization under sunlight;

(2), after seed soaking is basked seeds, seed is positioned in 30 DEG C of water that contain carbendazim, to soak after 48-72 hour and pulls out, with clear water repeatedly rinse clear to water till, then drain moisture content, save backup;

(3) nutrient discs is grown seedlings mid-March---and mid-October, when temperature is not less than 8 DEG C, the planting seed that step 2 is obtained, in the nutrient discs of matrix is housed, is cultivated the seedling of sprouting, and after two months, little transplantation of seedlings, to land for growing field crops, is carried out to conventional field management.

Preferably, in the present invention, seed soaking refers to seed is positioned in 30 DEG C of water that contain carbendazim and soaked, and wherein, 500g seed adds 3-4g carbendazim, water cover is crossed seed, every 4 hours of soak period---within 6 hours, change the water that once contains carbendazim, after 48-72 hour, pull out, with clear water repeatedly rinse clear to water till, then drain moisture content, save backup.

Preferably, in the present invention, described nutrient discs specification is 6cm × 6cm or 10cm × 10cm, and described matrix is the peat soil mixing after sieving.

Conventional vernalization step in the current asparagus cultivation of simplification of the present invention, seed after basking seeds, soaking seed is directly sowed to nutrient discs and cultivated, be colonizated in again large Tanaka, carry out conventional field management, asparagus process of growth damage by disease and insect reduces agricultural chemicals access times less, improve output, per mu yield can reach 4000 jin.

Embodiment

Below in conjunction with embodiment, the present invention will be further described, and embodiment implements as prerequisite taking technical solution of the present invention, provided detailed embodiment and concrete operating process but protection scope of the present invention is not limited to following embodiment.

Embodiment 1

(1) bask seeds: temperature is at 25 DEG C---between 30 DEG C, select fine day, under sunlight, asparagus seeds is directly shone to 6h---8h;

(2) seed soaking: after basking seeds, seed is immersed in the water that contains carbendazim, every 500g seed adds 3g---4g carbendazim, water surface lid is crossed seed, and water temperature is controlled at 30 DEG C, and every 4-6h changes the water that once contains carbendazim, soak and pull out after 48-72 hour, with clear water repeatedly rinse clear to water till, then drain moisture content, save backup;

The asparagus seeds that the present embodiment is selected is rich No. 1 of Zhejiang.

(2) nutrient discs is grown seedlings

In mid-March---mid-October, when temperature is not less than 8 DEG C, in 6cm × 6cm nutrient discs, pack matrix into extremely apart from aperture 1cm, compacting, the planting seed that step 1 is obtained is in matrix, and 1 seed of every hole sowing, is after planting covered to hole by matrix full, slightly compacting, described matrix is the peat soil mixing after sieving, and after planting applies Nitrogen, Phosphorus and Potassium, 7～8 kgs/acre, after fertilising, cover seedling dish with water, after fertilizer dissolves, discharge in time; Later every 15-20d, then supplementary fertilizer 2 times, fertilization mode is with identical for the first time; Keep during this time ground temperature at 8 ~ 25 DEG C, soil moisture is no less than 70%; Cultivate after 2 months, treat that the seedling of seed germination grows into 25～30cm, every young plant terrestrial stem terrestrial stem reaches 3-4 strain, seedling is transplanted to land for growing field crops and carry out field planting; In practical operation, also can use 10cm × 10cm nutrient discs.

Selection of land gesture is smooth, loosing soil, be rich in organic matter, good water permeability, draining fetch water sandy soil or loam ground field planting easily, 25-35 days after field planting, trench digging is executed Nitrogen, Phosphorus and Potassium (clear garden post-trenching in autumn), executed once thin night soil liquid fertilizer every 15-25 days, treat that asparagus grows to 25-35cm left and right, the tender tips of bamboo shoot are not bloomed for good, more than 12 degree start to adopt bamboo shoot.According to the present embodiment method through basking seeds, seed soaking, nutrient discs carry out asparagus Zhejiang of gathering after conventional field management rich No. 1 after growing seedlings, per mu yield can reach 4000 jin, and in process of growth, damage by disease and insect is few, reduces agricultural chemicals usage amount.
