Described fertilizing management specifically comprises:
1, spraying of foliage fertilizer:
Select rich 5128 as fertilizer sources of selenium, in grape flower bud differentiation, in the time of one week, spray for the first time, water carries out spraying on female of result and trunk of uniform and delicate after 100 times of dilutions by selenium rich 5128; The season of growth be blade grow up to yield positive results last until before gathering 20 days during in, water carries out spraying on blade and fruit ear of uniform and delicate after 200 times of dilutions by selenium rich 5128, every 12-15 days, sprays once, at least guarantees to spray for 4 times;
Spraying requires to avoid high light and rainy day, if meet rain after spraying in 8 hours, should respray, and guarantees that each medicine rate is more than 95%;
When blade grows up to, 99 plant protection, proteoglycan foliage fertilizer illustrate that by it spraying is on blade face, 5-7 days one time, finish for three times, and it is even, careful to spray;
2, the use of base manure:
Grape is selected rear branch and is stopped growing to before freeze-up, composite bacteria agent 48kg/ mu, middle trace element fertilizer 25kg/ mu, borax 2-3kg/ mu and copper sulphate 1-1.5kg/ mu are stirred, disposable the applying of ditching between two row vines, ditch depth 20-30 centimetre;
After bearing fruit, use proteoglycan 15kg/ mu, be watered 150kg 8-15 centimetre of dark the watering of ditching and execute between two row vines, then flat ditch.After this respectively water and execute once with same method with early June at the end of May.
3, supplementing of trace element:
Supplementing of trace element is mainly to determine according to grape growth nutrition condition.Specifically by grape leave growing state, judge the Condition of abundance or deficiency of various elements, then in corresponding period, supplement respectively.
1) mend potassium
See Lao Ye: blade tip is first dry, dry proof potassium deficiency in from the edge of leaf to leaf, in soil potassium deficiency magnesium is absorbed bad, so the color and luster of grape is bad.
The time of mending potassium is: mid-term is mid-June namely, 5-7 days one time, finish for continuous three times, and it is even, careful to spray.
2) mend magnesium
See Lao Ye: mesophyll is first yellow, yellow from inside to outside, as long as there is green this leaf not fall to having proved magnesium deficiency, magnesium deficiency grape color and luster is bad.
The time of mending magnesium is: early June, and 5-7 days one time, connect and spray three times end, it is even, careful to spray.
3) replenish the calcium
See the leaf growing up to: the point of blade can't pump out, such blade is to return symptom the morning of calcium deficiency.Grape calcium deficiency dehiscent fruit, decayed fruit, fruit ear are not of uniform size, then boron deficiency flowering time is different, have the large granule can not be ripe together.
The time of replenishing the calcium is: flower bud differentiation starts for one week, 5-7 days one time, and connect and spray 3 times end, it is even, careful to spray.
4) mend sulphur
See the leaf growing up to: under the tip of blade, refer to, represented a lack of sulfur, the grape fruit ear of a lack of sulfur is irregular.
Mending sulphur is to complete by trace element fertilizer 25kg/ mu in adding in the step of above-mentioned basal dressing.
5) mend copper
See the leaf growing up to: the most advanced and sophisticated side of blade refers to, represent to have lacked copper, it is little that grape lacks copper fruit grain length.
Mending sulphur is that the copper sulphate 1-1.5kg/ mu adding in the step by above-mentioned basal dressing completes.
6) mend boron
