Abstract

The invention discloses a field management method for cultivating asparagus. The method includes the steps of accelerating germination, sowing, planting seedlings in the field, managing compound fertilizer, managing water and fertilizer and reserving mother stems. According to the method, due to the fact that fine harmless management is performed in the asparagus growing process, disease and pesticide damage is reduced, applied organic fertilizer and NPK compound fertilizer are both pollution-free fertilizer, pollution to the environment is little, and the yield of asparagus is raised.

Description

A kind of field management method of asparagus cultivation

Technical field

The invention belongs to the field management method in agricultural planting field, particularly a kind of asparagus cultivation.

Background technology

Asparagus is the perennial root plant in Liliaceae Asparagus.It contains abundant histone, folic acid, nucleic acid, and the trace element such as zinc, manganese, molybdenum, selenium, chromium, and contain the effective components such as asparagine, quercetin, foreign Chinaroot Greenbier Rhizome saponin, coumarin and rutin, be universally acknowledged healthy food and anticancer food.Asparagus strong adaptability, easily cultivation, requires not sternly to temperature, also have few, the convenient management of recruitment, output advantages of higher in cultivation.

China's planting asparagus is mainly management and the production of extensive style at present, as thin in diameter, yield poorly, damage by disease and insect is many, the agricultural chemicals problem such as uses in a large number, how asparagus cultivation being carried out to fine-grained management, reduce damage by disease and insect and occur to improve Yield of Asparagus, is this area problem anxious to be resolved always.

Summary of the invention

The problems referred to above that exist for planting asparagus, a kind of field management method of asparagus cultivation is provided, asparagus cultivation is carried out to fine-grained management, to improve Yield of Asparagus, the present invention is achieved in that a kind of field management method of asparagus cultivation, in comprising the following steps:

(1) vernalization the first ten-day period of the March, with the water seed soaking 3-5 d of 30 ℃, drains and binds up with gauze with tide afterwards, is placed on vernalization at 25 ℃ of 20-, and with clear water drip washing 1-2 time, sow every day in the time having 10% seed to show money or valuables one carries unintentionally;

(2) broadcast and front furrow face is filled with to vola moisture in the soil water, until water ooze lower after, accomplish fluently straight line by 10 centimetres of seeding row spacings, to urge the seed simple grain program request of bud on crosspoint, then with sieve, soil is sieved equably on furrow face, the thick 2 centimetres of left and right of earthing, can field planting in the time that seedling grows to 25-30cm after two months;

(3) field planting is arrived Seeding planting among the booth of 45x6m, before field planting, and every mu of seedling field organic fertilizer 3000-5000kg, every mu of field planting 1200---1500 strain, the degree of depth of field planting is 3-4cm;

(4) 25-35 days after composite fertilizer's management field planting, ditching-fertilizing, ditch depth is 25cm, and ditch bottom width is 25cm, and the exit or entrance of a clitch is wide is 40cm, in seedling root, 20-25cm opens shallow ridges, execute Nitrogen, Phosphorus and Potassium, fertilizing amount is 25 kilograms, every canopy, executes at quarterly intervals Nitrogen, Phosphorus and Potassium one time, seedling seedling grew to 1.5-1.8m after 6 months, on total rhizome, was no less than 12-20 strain;

(5) after water and fertilizer management field planting, executed once thin night soil liquid fertilizer every 15-25 days, in 1 year, be no less than 8 times, 15 kilograms, every mu of urea, will water during this time, and fertilizing amount is by pure nutrition calculation, be not less than 50% of annual nutrient, after fertilizing in autumn, on root, soil thickness reaches 8-10cm;

(6) retain the stubble is gathered after end spring, every dish retain the stubble 3 strains---4 strains, and pinching is highly 1m, summer, every dish retain the stubble 4-5 strain, pinched not higher than 1.15m.

The present invention, by asparagus process of growth is carried out to innoxious precision management, reduces damage by disease and insect and occurs, and fertilizer and the Nitrogen, Phosphorus and Potassium executed are nuisanceless fertilizer, and environmental pollution is little, has improved Yield of Asparagus, and 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 take 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) vernalization asparagus seeds skin depth is hard, has cured matter water suction difficulty outward, broadcasts front necessary vernalization, the first ten-day period of the March, first carry out seed with cold water and winnow, float jejune flat kind and the kind of damaging by worms, with the water seed soaking 3-5 d of 30 ℃, after seed fully absorbs water, drain and bind up with gauze with tide afterwards, be placed on vernalization at 25 ℃ of 20-, for preventing vexed kind, with clear water drip washing 1-2 time, can sow No. 1, asparagus seeds Wei Feng island in the present embodiment every day in the time having 10% seed to show money or valuables one carries unintentionally.

(2) broadcast and front furrow face filled with to vola moisture in the soil water, until water ooze lower after, accomplish fluently straight line by 10 centimetres of seeding row spacings, to urge the seed simple grain program request of bud on crosspoint, then with sieve, soil is sieved equably to the thick 2 centimetres of left and right of earthing, after planting covered with plastic film immediately on furrow face.Keep daytime 25-30 ℃, night 15-18 ℃, can field planting in the time that seedling grows to 25-30cm after two months.

(3) it is smooth that field planting field planting soil is selected physical features, loosing soil, be rich in organic matter, heat absorption capacity is strong, good water permeability, subterranean water level is low, draining fetch water sandy soil or loam plot easily, build 45x6m booth, before field planting, 3000 kilograms of every mu of seedling field organic fertilizers---5000 kilograms, after the uniform of application of seedling field, with the rotovator 2-4 time that stirs, rake, again by between seedling transplant field, the degree of depth is 3-4cm, then the nature that waters is steady and sure, Deng water ooze lower after, the soil moisture conservation of in good time loosening the soil, line-spacing is no less than 1.4m, between spacing in the rows 25～32cm, every row is put two, rope, to prevent seedling lodging, every mu of field planting 1200---1500 strain, after seedling field planting, as find that there is grass, should root out.
