Line pepper yield increase fertilization

First, the fertilization standard  

At present, the potassium content in the soil can only meet the general yield 100 - 125 kg of pepper needs, in order to further increase pepper production 100--150 kg, 5.25 kg of potassium to be pure, equivalent to 13.2 kg of potassium sulfate. The utilization rate of potassium sulfate is only 40 % - 50 %, so the actual application amount in production should be 20 - 25 kg. According to 250 kg per mu pepper plots, should be applied per acre of potassium 20--25 kg urea 20--25 kg, 20 kg of DAP, manure 1000--2000 Gongjin as base.  

Second, the fertilization period  

50% potassium sulfate and urea, diammonium pepper seedling transplanting in the first half into the planting furrow open strip groove, and promptly soil as fertilizer; the remaining 50% of potassium sulfate, urea and diammonium wheat harvest after clip When the line is used as a top dressing .  

Third, the growing season foliar spray fertilizer  

Foliar spraying can be carried out with urea plus potassium dihydrogen phosphate or biological potassium fertilizer during the bud and knot phase of the pepper. Spray concentration: 1 % urea and 0.5 % potassium dihydrogen phosphate . The specific operation is: every 100 grams of urea,   50 g of dipotassium phosphate was 15 kg of water . Per acre spray 42--45 kilograms of fertilizer solution; note sunny 10 am spray --12 4 or when pm - 6:00; uniformly sprayed on both surfaces of the blade; interval 7--10 days and then sprayed better.
