Apple Garden summer tube misunderstanding to avoid quickly
Do not water in summer drought
In general years, summer drought often occurs in June, and it lasts for a long time. This is the fruit tree flower bud differentiation period and young fruit expansion period and the fruit tree water requirement fertilizer critical period, many farmers are afraid that washed flower buds can not water, this is wrong. At this time, watering is not only conducive to flower bud differentiation but also conducive to fruit cell division, while the first fruit cell expansion can reduce the occurrence of micro cracking on the fruit surface in autumn.
Single fertilizer application
The growth of fruit trees needs comprehensive nutrition and single fertilization. Both nitrogen fertilizers and phosphate fertilizers and potash fertilizers are detrimental to the growth and development of fruit trees. In June, fertilization should use light nitrogen to replenish phosphorus and potassium, and at the same time, it should be sprayed with foliar fertilizer to apply trace elements, and water should be used for irrigation. Calcium Amino Acids and a 1:5 Amino Acid Fertilizer are applied to the tree trunks to do everything possible to meet the nutrients needed for the growth of fruit trees and balance the supply.
Dung (urine) into the park
The farmer's idea of ​​"producing dirt on the ground," is talking about the dangers of raw manure. Organic manure, such as human waste and animal manures such as pigs, chickens, sheep, and rabbits, will burn roots if they are not directly fermented into the garden. Where organic fertilizers have to be crushed for more than 1 month, they can be applied to the orchard.
Improper bagging time
The bagging is too early to affect the development of young fruit; when the bagging is too late, the fruit surface is poor and the color is not good. Should be pushed back from the plan selling fruit time, the early ripe fruit is bagged 85 to 90 days before the fruit is sold, the middle ripe fruit is bagged 90 to 100 days before the fruit is sold, the late ripe fruit is bagged 110 to 120 days before the fruit is sold, even if The Fuji apples that were sold for Mid-Autumn Festival were also counted down 95 to 100 days from mid-September.
Improper twister operation
Spinning the new branch 90 degrees, I wonder if the base will emerge a new branch. The correct way is to change the direction from standing 90 degrees to 60 degrees to 45 degrees oblique, so you will not take a new bar, and it is not easy to sprain the sprained branches. In addition, new shoots must grow to 15-20 centimeters and twist.
Improper handling of branches
On the back of a powerful new strong branch, and the top of the middle and long years of the previous year, either completely spared, or did not dare to move. The correct course of action is to leave leaves at the base for topping, and before June 15th it is possible to cultivate regenerated flower buds. Too late to consume nutrients and not conducive to re-flower buds.
The timing of rot control is not correct
The rot disease is not prevented during the growth period, but is treated during germination. June-August is the peak period of fruit tree growth. During this period, 25% tebuconazole or 70% thiophanate-methyl 800-1000 times solution should be used for branch painting or spraying, which can effectively prevent the occurrence of spring rot disease.
