Potassium humic acid( other name: potassium humate, potassium fulvate potassium fulvic humate) is a multi-functional plant growth and drought-resistant nutrient, with the effect of water saving and drought resistance, flowers and fruit protection. On the effect test on grapes, it discusses the influence of this product on the quality and production of grapes, and provides the basis for the large use of it on grapes.
The effect test of potassium humic acid on grape
Material and method
1. Test varieties
Fujiori grape
2. Test treatment
Per 665㎡ dissolve 100g this product into 50 kg water for spraying fertilization. Use early in the results.
3. Test method
This test conducted multi-regional comparison test and repeated 6 times. The 10 vines in each area were selected with consistent growth for the designated test and production test. Spray it at 3-4 pm. Other management methods are the same as the non-test grapes. Production for statistical analysis.
Results and Analysis
1. Potassium humic acid can promote early ripening of grapes
According to the fruit maturity test on the same day of the same month, the treatment of spraying fertilization, grape maturity is 95%, increased by 20% compared with the control of 75%. It can be seen that potassium humic acid has the effect of promoting ripening, generally can be picked 3-7 days in advance.
2. Potassium humic acid can improves grape quality
2.1. Increase the sugar content of grapes and increase the sweetness
The determination of sugar content showed that the sugar content after treating by spraying fertilization was 11.8 degrees, 0.6 degrees increased compared with 11.2 degrees. Thus: the initial spraying fertilization can improve the sugar content and sweetness.
2.2. Improve grape quality and increase commodity performance
After the grape mature, the appearance quality test showed that: Spraying fertilization treatment, the diameter of single fruit increased 0.4cm, single fruit weight increased 0.4g, fruit bigger and heavier, sell good price in the market.
Thus it can be seen that after the grape spraying fertilization of potassium humic acid, its grape quality was greatly improved. The commodity nature improved significantly, and increased the economic benefits.
3. It can improve grape single production
Grape can increase the yield per plant after spraying it. The test results showed that the average yield after spraying fertilization was 4.45 kg, increase 0.45 kg and 11.25%. Analysis of the reasons for increasing yield: the initial spraying fertilization can promote the transport and storage of nutrients to the fruit, increase the weight of a single fruit, and improve the yield of a single strain.
Summary
1. In the early stage, of spraying potassium humic acid can improve the sugar content, improve the appearance quality, increase single fruit weight and improve the yield of a single strain.
2. In the early stage of fruit, spraying potassium humic acid 100g, add 50 kg water per mu. In case of drought period, the spraying should be increased.
The above is all the contents of the effect test of JINGFENG HUMIC ACID in potassium humic acid on grapes.
