The whole period of grapes with fertilizer program

1. Bleeding period: spring is warm, the temperature rises, the root system starts to germinate, and the fluid starts to flow and wake up from dormancy. Bleeding is a normal physiological phenomenon.

2. Pompous growth: the injury flow ends, pompous growth begins, and then the winter bud scales crack and green buds can be seen.The best time to clear the garden in spring is when the pompoms are green.Recommended use of imported sulfur 500 times + chlorpyrifos 500 times clear garden.The task of spring is not to fertilize (mainly with the stored nutrients of the previous year), but to promote roots.It takes about 40 days from the eye to the beginning of flowering.

3. Spread 2-3 leaves: when 2-3 leaves are unfolded, 

4 kg root cattle are irrigated with drip irrigation.

Inflorescence showing: 5-6 leaves spreading, inflorescence clearly visible.The next six leaves are in the 1-cardiac phase (about 20-25 days after germination, the sixth leaf has grown to a third of its normal size).Drip irrigation was applied with 2kg potassium dihydrogen phosphate + 1kg balanced water soluble acarboxylate + 2kg root cattle, foliar spray express 800x + capromethole 2000x + pyrazole ether ester 2000x + imidacloprid 1500x.

5, inflorescence separation stage: inflorescence constantly elongate and grow, flower buds separated from each other.At this time, leaf spray cover mg le 2000 times + fast food 800 times +2.5 times of water and milk kung fu permethrin 1250 times + suk ling 600 times.

6. Incipient flowering stage (or flowering stage) : 5% of the flower bud petals fall off like a cap, drip irrigation of 2 kg potassium dihydrogen phosphate +2 kg balanced water-soluble fertilizer ai can yield 20-20-20+TE, combined with 2 kg compound fertilizer 15-15-15.

7, full flowering: more than 90% of the flower bud petals cap off or top up, at this time rinse 5 kg nutricin calcium, xie hua about 10% is the best calcium supplement time, calcium absorption utilization rate is the highest, is the whole physiological period 80% calcium demand.Foliar spray fastol 800 times + gamethyl 2000 times + benzpyrimidine 1500 times + chloramidine 1500 times.

8, physiological fruiting stage: flower residues (flower cap and white filament) fall off, the young fruit is not immediately expanded, but experienced a period of physiological fruiting stage.The fruit is not seated until it begins to swell.If after fruit protection treatment, generally can sit, after treatment, the use of ai can harvest balance fertilizer formula 20-20-20+TE, 5 kilograms per mu, this period of air humidity large fruit protection effect.

9. Small and young fruit stage (first expansion stage) : this stage shows rapid cell division and later expansion, which is a critical stage of nutrient demand. After the treatment of leavening fruit, 5 kg of balanced fertilizer (20-20-20+TE) was applied to one mu of soil.Use it again before entering the hard core phase.

10. Hard core stage (earthing stage) : from the appearance, the growth rate slows down or even stops, seed coat begins to harden, embryo development accelerates, and the formation of seeds requires the participation of calcium and magnesium. At this stage, 2kg of nutrasin calcium +15-6-35 acaricol high-k soluble water fertilizer 3kg + 2kg root cattle can be washed.

11. Secondary expansion: this is also the peak period of nutrient demand, during which the pulp cells continue to expand, the cell walls begin to thin, and the fruit becomes slightly soft when pinched.While it doesn't look much bigger on the outside, there's a dramatic change inside, with berries having the highest acid content and starting to accumulate sugar.In this period, we can use the formula of phosphorus and high potassium in micro nitrogen, 7-12-40+TE, 4 kg +2 kg root cattle per mu, and at the same time, we need to add a calcium, 5 kg nutricin calcium, to improve the flavor, increase the fruit powder, and promote the coloring.

12, mature phase: the goal of this phase is to reduce acid and sugar, promote coloring.This period of fertilizer nitrogen content must not be high, no more than 10.Continued use of 7-12-40 high-potassium water-soluble fertilizer ai can yield 5 kg/mu, nutritaphosphorus potassium 5 kg/mu once 15 days before maturity, to promote the accumulation of fruit nutrients.Close to the park to control the water.

After 13, collecting leaves (1 month before the time the most appropriate) began to fall fertilization: recommended 1000 kg organic fertilizer + 150 kg bacterial manure + 25 kg 16-8-18 slow controlled release fertilizer, organic fertilizer can be artificial fermentation in advance, give priority to with cow sheep droppings, to join the crop straw, corn, soybean straw can, according to the dung: straw and give priority to, cover high temperature plastic fermentation six months or so, can reduce the cost.
