In the previous article, we talked about the effect of mineral potassium humate on the fruit setting rate of apples. This article continues to explain the effect of mineral potassium humate on the fruit setting rate of Anli.
1. The effect of mineral potassium humate on the fruit setting rate of Anli inflorescence
The rules of the two low-lying test sites show that the results of 500 times liquid, 1000 times liquid and clear water control have reached extremely obvious levels in both sites, among which 500 times liquid has the best effect.
2. The effect of mineral potassium humate on the fruit setting rate of Anli flowers
The data show that the test results in the two sites have the same rules. The improvement of Anli flowers and fruit setting by 500 times and 1000 times liquid has reached a significant level, among which 500 times liquid treatment has reached an extremely obvious level.
Summary
1. The results show that spraying 3000-5000 times of mineral potassium humate during the flowering period has increased the fruit setting rate of Marshal, Mutsu, Golden Crown apples and pears to varying degrees, and the effect decreases with the decrease of concentration. It can be concluded that mineral potassium humate is a new method to solve the low fruit setting rate of some apples and pears.
2. Spraying mineral potassium humate during the flowering period can indeed increase the fruit setting rate of apples, but the treatment reactions of different varieties are not the same. Marshal apples require a lower concentration, and 2500 times solution is the best, while the high concentration of 500 times solution is not obvious. Mutsu apples require a higher concentration, with 1000 times solution being the best, followed by 500 times solution, and 2500 times solution also reaching a significant difference level.
3. Spraying mineral potassium humate during the flowering period of Anli, the reaction of increasing fruit setting rate to concentration is not completely consistent with that of apples. Experiments in different years and different regions have shown that 500 times solution is the best. The comparison of 1000 times solution with the control also reached a significant level, and its effect decreases with the decrease of concentration.
4. On Golden Crown apples, the results of applying mineral potassium humate at different periods showed that the best effect was sprayed during the flowering period, while it was ineffective during the balloon period.
