Misunderstanding of Apple Orchard Management in Summer

1 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.

2 Single fertilizer application

The growth of fruit trees needs comprehensive nutrition. A single fertilization, whether nitrogen fertilizer, phosphate fertilizer, or potash fertilizer, is detrimental to the growth and development of fruit trees. In May-June, fertilization should lightly concentrate nitrogen and phosphorous and potassium, and at the same time, apply trace elements fertilizer and water to the leaves. Apply high-calcium amino acids, apply 1:5 amino acid fertilizer to the trunk, and do everything possible to meet the nutrients needed for the growth of fruit trees. Balance the supply.

3 Fertilization is too concentrated

Digging trenches, digging pits, circling facilities, and concentrating facilities can be applied to saplings up to 4 years old. However, fertilization should be carried out along with trees in the full fruit period to achieve proper, clever, shallow and uniform application. Clever match, shallow Shi (10 ~ 15 cm), uniform application, according to the strength and weakness of the tree Shi, change a flattening fertilization method.

4 raw manure (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.

5 fertilization can not be required by the tree

The fertilization time in summer should be from mid-May to mid-June. Many people in production are trying to make use of the facilities when they are priests. When they have money, they buy when they have money and buy them.

6 Improper selection of 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.

7 selection bags only price not see quality

A good quality bag not only has good greening, but also has a good fruit surface. If the fruit is large, the black and red spots are small, and the secondary bag is the opposite. Fruit bag selection method: wood pulp paper bag does not distort after being ignited by fire, and can be picked up by hand; straw pulp paper bag and recycled paper bag lose their original shape after being ignited by fire, appear gray, fragile, and cannot be taken. Wood pulp paper bags should be used.

8 diagrams do not figure the effectiveness of bagging

Generally, there should be 14000~15000 bags per mu for aquapark, and 10,000 bags for dry land. The purpose of bagging is to sell more money. To sell more money must be quality-winning, three to three, or as good as two-hundred and five tenths. Too much tree-bagging consumes a lot of energy, and it is easy to form a man-made size year, leading to rot disease.

9 Twisting tip improper operation

Spinning the new branch 90, I wonder if the base will emerge a new branch. The correct way is to change the direction, from the vertical 90 to 60 ~ 45 can be oblique, so that will not take a new bar, and sprain the sprains easily sprain. In addition, new shoots must grow to 15-20 centimeters and twist.

10 new branches and fruit axe missed topping

The shoots of the new shoots and the fruit shoots of the axillary shoots must retain 8 to 10 leaves, so that the regenerated shoots can easily become flower buds, but the time should be set before June 15. The problems that arise in production are the fact that the topping is too small to form one for one, and the second is to pick out the heart for no flowers.

11 branches are not handled properly

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.

12 The timing of rot control is not right

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.

13 watering fear workers, busy in weeding weeding

When watering, soil conditioners are added to avoid deep plowing. Grass spray and paraquat can be used for 20 to 25 days. At the same time, the orchard temperature can be lowered to loosen the soil and serve two purposes.
