Description
Technical field
The invention belongs to arid, semiarid zone agricultural water-saving irrigation technical field, specifically a kind of bilayer alternate covering
The fructus lycii drip irrigation cultivation method of stalk.
Background technique
The shortage of northwest China regional water, drought, evaporation capacity is bigger than normal, and the extensive irrigation method of traditional agriculture is not
Adapt to the sustainable development of local agricultural.Fructus lycii irrigation is most commonly seen in a manner of flood irrigation and furrow irrigation, this is not only wasted greatly
The water resource of amount, while making some areas level of ground water increase, leading to the soil salinization, the chemical fertilizer that flood carries penetrates into ground
Under, serious pollution is caused to groundwater resources.In recent years, with the continuous development of water-saving agriculture and the ecological agriculture, trickle irrigation
Technology is received by broad masses of the people.Improving straw mulching technology has been developed in recent years to have and keeps soil moisture, increases
Add the novel agronomic technique of crop yield.Traditional single technical application it is more, the present invention is making full use of the rain furrow collection that edges down
On the basis of rain, trickle irrigation and covering are conjointly employed in medlar cultivation, not only make full use of the moisture wet characteristic and section of trickle irrigation
Water dispenser system can preferably keep soil moisture and reduction soil moisture using improving straw mulching to reduce invalid moisture
Evaporation, and irrigation method is optimized on the basis of fructus lycii traditional irrigation, finally make medlar cultivation in water utilization, quality, production
Amount etc. is with the obvious advantage.
Summary of the invention
The purpose of the present invention is to provide one kind can be improved yield of medlar, and the fructus lycii trickle irrigation cultivation side of water-saving fertilizer-saving
Method.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of fructus lycii water-saving drip irrigation cultural method of bilayer alternate covering stalk, specifically includes the following steps:
1. fructus lycii cuttage seeding is handled: by current year raw semi-lignified, the middle part of the sturdy cuttage seeding branch of diameter 1cm is cut into
Every segment length 8-10cm, the cuttage seedling with 2-3 seed bud；By EM bacteria agent, potassium silicate and water according to the ratio of weight ratio 1:2:200
Example is prepared by mixing into soak；Cuttage seedling is put into soak, in 25-28 DEG C of environment, is impregnated 5-8 hours, after taking-up
Giant favours 45 degree of angle impact sand grounds of sand ground, goes out the dell of a depth 50cm, the chitosan for being 1% with mass concentration
Cuttage seedling, is then put into dell and carries out Sand culture by spray solution cuttage seedling, spare；
2. plant in ditch: soil deeptillage, site preparation ridging, the high 25-30cm in ridge, ridge top is smooth and is width 40-60cm, ridge bottom width
Fructus lycii cuttage seedling is dug cave plant in kind of planting ditch in late March by 120-140cm, ditch bottom width 30-50cm, cave depth 40cm, strain
Away from 100-150cm；Calcium, Chelated Manganese, chelated magnesium, phenylalanine glycine betaine, vitamin C and water will be chelated according to 0.5:0.1:0.2:
The ratio of 0.6:0.3:500-1500 is mixed and made into nutrient solution, and fructus lycii cuttage seedling is put into the sprinkling nutrition of planting hole back root part
Liquid, then earthing is filled and led up, and nutrient solution fountain height is every plant of 10-50mg；
3. being laid with drip irrigation zone: being laid with a drip irrigation zone, water dropper spacing 12-24cm in kind of planting ditch, and drip irrigation zone is apart from Chinese holly
Qi seedling 10cm；Then stalk bilayer alternate covering formula is carried out in fructus lycii kind planting ditch earth's surface to be laid with；
4. spring irrigation: after the plant of fructus lycii cuttage seedling, potassium humate being added in irrigation water, every cubic metre of irrigation water is added
0.3kg potassium humate；It carries out trickle irrigation 4-6 hours daily, continuous to irrigate 3 days, the amount of dripping is 18-24m per acre for control3；
5. drop applies liquid manure: by urea, Pig dung and urine, amino acid selenium, fulvic acid, xylose mother liquid, Tea Saponin, jasmonic, EM bacterium
Agent and water are that the ratio mixing of 3-5:10-20:0.1-0.4:1-3:2-4:0.1-0.5:0.1-0.3:1-2:100 is set by weight
In fermentation vat, aerobic fermentation 10-15 days, 100 mesh nylon screen filtrations, filtrate was liquid manure, by liquid manure be added to irrigation water into
Row trickle irrigation, every cubic metre of irrigation water are added 2-3kg liquid manure, carry out trickle irrigation 4-6 hours daily, continuous irrigation 2 days, per acre the amount of dripping
For 20-30m3, primary, the first tenday period of a month in May to late May, which is irrigated, respectively at the first tenday period of a month in early April to May irrigates primary, late May to 7
Month last ten-days period irrigate irrigated three times with late August it is primary, altogether plus water and fertilizer irrigation 6 times；
6. winter irrigation: before entering the winter, the nutrient solution of step 2. is uniformly sprayed on the mixed straw of covering, plough in time by
Mixed straw ploughs under in ground, and fountain height is that every kilogram of stalk sprays 0.2-0.3kg nutrient solution, carries out winter irrigation after ploughing, daily into
Row trickle irrigation 2-4 hours, continuous to irrigate 2 days, the amount of dripping was 12-15m per acre3。
Preferably, being dripped after being down to 4-6 DEG C added with the irrigation water temperature of liquid manure when late August imposing liquid manure
It fills.
The stalk is broken wheat straw and corn stover, wherein broken wheat straw length is 15-20cm, corn stover is mechanical through whole stalk
Crush processing, length 110-130cm.
The stalk bilayer alternate covering formula is laid with, and specifically first uniformly spreads one layer of broken wheat straw, overlay capacity 450-
600kg/ mus, broken wheat straw top uniformly spreads one layer of corn stover, and overlay capacity is 500-650kg/ mus, and corn stover is along fructus lycii kind
Band covering is planted, broken wheat straw and corn stover press stalk length direction positive quadraturing laying.
The beneficial effects of the present invention are:
1, the present invention is directed to semiarid and arid soil and climatic characteristic, handles by using fructus lycii cuttage seeding, furrow
Efficiently collection rain, in ditch trickle irrigation plant, spring irrigation, winter irrigation and drop apply liquid manure, a series of measures such as bilayer stalk alternate covering in ditch, mention
High rainfall and efficiency of water application is irrigated, reduces water resource waste, compared with traditional flood irrigation cultivation, total output is improved
15.13%, superfine fruit rate improves 13.6%, and third class fruit rate reduces 4.6%, and the dry fruit 100-grain weight that is averaged increases
14.44%；Protein content increases 2.53%, and polyoses content increases 10.42%, and carotenoid content improves
45.169mg/100g。
2, prolonged application traditional irrigation method will cause soil shallow-layer salinity aggregation content and rise, in turn results in soil
Raw salination, thus the present invention utilizes improving straw mulching, the integrated measure of trickle irrigation liquid manure, not only ensure that needed for fructus lycii growth
Nutrient and moisture, and make total salt content in the soil shallow-layer of plant barbarum without dramatically increasing, and with year
Total salt content of the growth of limit, soil shallow-layer gradually decreases, and improves the situation and sand of soil secondary salinization
Physicochemical property.
3, the present invention carries out spring irrigation after fructus lycii transplanting, accelerates the speed that fructus lycii roots in sand, makes
It obtains fructus lycii to be quickly colonized in soil, enhances the anti-blown sand ability of fructus lycii.
Detailed description of the invention
