Summary of the invention

The object of the invention is just to provide a kind of booth spring asparagus lettuce cultivation method for premature.

The present invention is achieved by the following technical solutions:

A kind of booth spring asparagus lettuce cultivation method for premature, comprises the following steps:

(1) kind is selected: should select the early-maturing variety that cold resistance is stronger;

(2) site preparation and fertilization: select loosing soil, well-drained sandy loam, every 100-120cm place, dig a hole, cheat dark 30-40cm, cheat diameter 10-15cm, in each hole, put the mixture 70-80g of fish intestines and fish-bone, cover one deck pericarp above, tamp with former sandy loam afterwards, water permeable, wait soil naturally dry, mu is executed soil conditioner 30-45 kilogram, the shallow soil that ploughs under again;

Described soil conditioner is made up of the raw material of following weight parts:

Zeolite powder 3-5, nanometer actinolite powder 4-5, medical stone powder 15-20, weathered coal 15-20, urea 4-5, ferrous sulfate 3-5, grape furancarboxylic acid zinc 3-4, ethoxylated trimethylolpropane triacrylate 2-3, distiller's dried grain 2-3, ginger oil 1-2, sodium phosphate trimer 1-2, astragalus polyose 0.1-0.2;

Above-mentioned sodium phosphate trimer is joined in 10-20 times of water, after stirring, add zeolite powder, medical stone powder, weathered coal, be heated to 70-80 DEG C, be uniformly mixed to water dry, add the each raw material except astragalus polyose, under room temperature, mix and stack 4-6 hour, add astragalus polyose, stir, dry, granulation, obtains described soil conditioner;

(3) begin sowing in good time: general late September to early October is sowed, and first carries out seedbed before sowing, waters vola water, seed is mixed to dry fine earth uniform broadcasting, after planting lid layer fine earth, covering film;

(4) field planting in good time: get final product field planting in the time of asparagus lettuce seedling tool 4 leaf, before field planting, soil in booth is ploughed deeply and suned the earth which has been ploughed up, use sufficient base manure, execute well-rotted farmyard manure 3000-3500 kilogram for every mu, urea 40-50 kilogram, slowly-releasing potassium dihydrogen phosphate 20-30 kilogram, the preparation of described slowly-releasing potassium dihydrogen phosphate comprises the following steps:

Take potassium feldspar, methyl methacrylate, sodium phosphate trimer, polyvinyl alcohol, gelatine that mass ratio is 60-70:10-20:3-5:1-2:1, potassium feldspar is calcined at 600-700 DEG C to abrasive dust after 1-2 hour, join in 5-10 times of water, add sodium phosphate trimer, stir fully, add gelatine, methyl methacrylate, rising temperature is 75-80 DEG C, insulated and stirred 10-15 minute, adds polyvinyl alcohol, 1600-2000 rev/min of dispersed with stirring 10-20 minute, obtain dispersion liquid, dispersion liquid is sprayed application on biphosphate k particle, dry, to obtain final product;

After field planting, water normal root water;

(5) field management: want will add forced ventilation daytime after field planting, control temperature of shed is 15-25 DEG C, and will suitably be incubated night, temperature should be lower than 5 DEG C, and while there is at later stages flower a kind of sedge, the colored a kind of sedge that tender stem can be differentiated is removed, and promotes stem continued growth;

(6) results: concordant with siphonal lobe or just showed when bud as Harvesting Date taking lobus cardiacus, can gather as required in batches.

Advantage of the present invention is:

Asparagus lettuce cultivation method of the present invention is scientific and effective, by to potash fertilizer slowly-releasing, and being coated trace element, can ensure micro-long run supply, more phosphate fertilizer, calcareous and nitrogenous fertilizer can be provided, can improve the assimilation effect of asparagus lettuce, for asparagus lettuce provides better nutrition, guarantee asparagus lettuce is grown fast.
