Potassium Nitrate Compound Fertilizer- Special Fertilizer For Fruit And Vegetable

1. The composition of potassium nitrate compound fertilizer:
(1)Total nutrient content of phosphorus and potassium is ≥ 46% [15-13-18]
(2)The amount of trace elements is ≥ 20%
(3)The nitrate nitrogen is ≥ 40%
(4)OA activation organic fertilizer is ≥ 10%,OA activator is ≥ 10%,contains chelated trace elements.

2.National standard:GB15063-94
3.Agricultural registration certificate:NY-2000-006
The function of potassium nitrate compound fertilizer:

 Compared with potassium chloride and potassium sulfate, potassium nitrate compound fertilizer has the characteristics of fast nitrogen absorption, high fertilizer utilization rate and good crop quality.
(1)It can provide nutrients and trace elements needed for crop growth, can effectively improve soil, promote crop metabolism.
(2)Can prevent crop physiology to metabolize maladjustment, plant tufted, dwarfing; It can also prevent narrow leaves, white texture, slow green, and root rot at seedling stage, and can effectively prevent red blight, thus achieving the effect of increasing yield and income. The yield per mu can increase by 10-15%.For cash crops, the utilization value is higher. For example: tobacco can improve the grade, soybean rape can improve the oil yield, vegetables, fruits, sugar cane can improve the appearance and taste. 
(3)The most distinctive function of self is to improve the color, taste, quality and resistance of crops.
(4) Long-term use, can automatically adjust the relationship between soil, water, air, fertilizer four. It can also improve the quality and of soil, water, gas, fertilizer, and also can optimize the ecological environment. 
Key points of product fertilization:
  For forest fruit: before use, stir OA activated organic fertilizer and forest fruit special fertilizer evenly before use. When fertilizing the fruit trees, pay attention not to be too close to the root, mainly depending on the age of the trees and different soil application, general adult trees before winter application of base fertilizer - special fertilizer for forest fruit 1 ~ 2 kg, spring application of top fertilizer 1 ~ 2 kg. Young tree fertilization is half of the amount of trees, the spring application of timely fertilization according to the regional climate. 

Used for vegetables and melons:
1.Base fertilizer: the base fertilizer adopts the method of full tillage and deep application. Before the cultivated land, the fertilizer is evenly applied on the field surface, and then the soil is turned over, so that it can be sown and turned over, with fine tillage and strict cover. 
2.Top dressing: top dressing is applied after 20 days for the selected plants. The method of top dressing is to spread the fertilizer evenly along the holes dug along the plants and then cover the soil. It is advisable to apply fertilizer 8 ~ 10 cm away from the crops.
Reference amount of product fertilization before use, first stir OA activated organic fertilizer and special fertilizer evenly, General use base fertilizer to apply special fertilizer 35-45 kg/acre, top fertilizer  is applied as apply special fertilizer 25-30 kg/acre.
