Excellent results of the present invention is as follows:
1. nutrient discharges and meets capsicum absorption requirement
The whole growing of capsicum, big to nitrogen, potassium requirement, need phosphorus less.Nitrogen, phosphate fertilizer all have remarkably influenced to the growth of seedling and the formation of flower, should suitably supply with.But nitrogen fertilizer amount can not be too much, prevents to cause plant excessive growth, and postponement is yielded positive results.In the period that be nitrogen, phosphorus the best fruiting period, the potassium demand is maximum, its quantity accounts for 57%, 61% and 69% of each self-absorption total amount respectively.Special-purpose control-release fertilizer utilizes fertile composite the forming of nitrogen, phosphorus, potassium controlled release of different time of releasing just according to this absorbing rule, can satisfy the special requirement of the different growth phases of capsicum to nitrogen, phosphorus, potassium three elements.
2. avoid the excessive harm of soil nutrient ionic concn in a short time to root system
The capsicum root system is the salt tolerant branch not, if present fertilizer variety improper use meeting of using works the mischief to capsicum.Capsicum is topdressed and mainly adopts the method that fertilizer fusing back is used with irrigation water, soil solution concentration is increased sharply, even if the fertilizer of using as base manure, if available nutrient content height, also may cause soil solution excessive concentration, unfavorable to the capsicum root growth.Nutrient ion in the special-purpose control-release fertilizer is that the absorption along with capsicum progressively discharges, and the soil solution is raise too much, has avoided the injury to root system.
3. fertilizer is concentrated to impose near the root system, improved fertilizer utilization efficiency
The capsicum conventional fertilizer application is that part fertilizer is executed near root system before transplanting, and most of fertilizer is with watering towards executing in process of growth.Because the capsicum root system is undeveloped, the root amount is few, and it is shallow to bury, and the fertilizer far away apart from root system is difficult to absorb, and causes utilization rate of fertilizer low.Special-purpose control-release fertilizer is near disposable all imposing on the root system before transplanting, and fertilization effect is good, the utilization rate of fertilizer height.
4. nutrient slowly discharges, and reduces fertilizer loss
Capsicum is the big crop of water requirement, must frequent watering in its process of growth, and after being manured into soil, common chemical fertilizer all exists with ionic condition, and soil is to nitrogen, potassium ion, and particularly the nitrogen ionic adsorption is poor, moves with moisture easily and causes loss.Special-purpose control-release fertilizer is present in the soil with the fertiliser granulates that is surrounded by putamina, and discharges along with the absorption of capsicum, and the ion that retains in the soil is few, and the loss of nutrient reduces.
