Apple orchard summer management, these 5 things must not be done
After the apple tree enters the summer, the young fruit begins to swell, and the flower bud differentiation has also begun. The focus of the orchard management in this period is to focus on this, but in the actual production, everyone has some incorrect practices, futile, counterproductive, and even contrary. Now there are five wrong practices. The measures are proposed, I hope everyone can pay enough attention to it and take it as a warning.
Not suitable for flood irrigation
The flood irrigation in the orchard in summer will easily cause the tree to grow and affect the differentiation of flower buds; if the drought is in the early stage and the flood irrigation in the later period, the water supply is uneven, it is easy to cause fruit splitting; when the summer is high, the flood in the orchard will cause a lot of flooding The capillary absorbs the roots and suffocates to death. Although the soil moisture content is large, the capillary roots can't work normally, and the water transfer is blocked, causing the leaves to transpiration and lack of water, resulting in burning leaves or leaf wilt. , The lower part of the fruit will be scalded to varying degrees. Therefore, watering should be irrigated with a small ditch, or combined with flushing and fertilizing water to supplement water and fertilizer in time to achieve high yield expectations.
Two should not apply nitrogen fertilizer
Most fruit farmers think that the fruit should grow up, and urea scatters hard. In the summer tube, nitrogen fertilizer is still relatively emphasized, resulting in the fruit tree not being able to stop growing in time, less flower bud differentiation, and serious results in large and small years. It will also cause the fruit to mature late, the color difference and taste will be light, and the quality of the fruit will decline. The correct approach is to increase the application of phosphorus and potassium fertilizers or low nitrogen medium phosphorus high potassium fertilizers and trace element fertilizers in summer.
Three should not be cleaned and weeded
Weeding in orchards should not be too diligent, so weeding the grass clean, it was laborious and laborious, and it did not make full use of the grass to protect the soil and fertilizer. To use grass reasonably, generally remove some malignant weeds, the rest should be controlled below 30 cm, when it is too high, use a lawnmower or manual plow to cover the tree disc in place, which can increase the soil organic matter content, and Moisture can protect the soil moisture, which is conducive to the healthy growth of fruit trees.
Four should not deep turn the tree tray
In recent years, orchards have increased in number of micro-cultivators. As long as it rains, many fruit farmers will turn the orchard deeply once, making it difficult to heal roots and weaken the tree. It affects the normal growth of fruit and the differentiation of flower buds. Deep turning should be carried out when applying base fertilizer in autumn and winter, and avoid turning deep in the growing season.
Five should not carry all the branches on the back
Pruning all branches on the back in summer will cause direct sunlight on the branches, causing sunburn, causing rot or dry rot; direct sunlight on the fruit will also cause sunburn. Cut one for the branches on the back, or cut off the dense branches, and use the space to pull the branches or twist the tip. Do not cut them all and shave your head.
In short, orchard management is a complex system process, especially the summer season is the most important in the growing season. I hope that the majority of fruit farmers will still have to scientifically manage, properly fertilize, and properly apply various technical measures after bagging to achieve greater economic benefits. And social benefits.
