Now that it has just entered June, many of the orchard's film bags have been set, so what should be done in the later stage? Summer is the season of high incidence of pests and diseases in orchards. The following will tell you about the occurrence of diseases and related agricultural work. Pests and diseases (1) Red spider Red spiders occur in May, breeding in June, and flooding in July. Although our first drug after the red flower and the flower has been eliminated from the wintering adults, we can't take it lightly in May and June. It is necessary to prevent the red spider that was leaking at the time. (2) brown spot disease The pathogen of brown spot disease mainly infects the old leaves, that is, the spring shoots begin to infect after the long-term stoppage, and the prevention time is in early May and early June. As long as there is rainfall, the orchard's humidity will start to infect, but the infected leaves will not cause leaves immediately. By the end of September in early August, as long as there is continuous rainy weather, the rain will stop after the high temperature, three days. There will be a lot of fallen leaves in the orchard. (3) rot disease The law of rot disease is summer infestation, autumn lurking, winter development, spring rotten skin. For the prevention and control of rot disease, the fruit trees should be coated in June, and the tree body should be preserved first, that is, the rod is in the tree, and the tree is in the garden. Topdressing and supplementing phosphorus Topdressing is to let the fruit trees eat. Just like people, when they are hungry, the same is true for fruit trees. It is now time to eat. 1. Farmers friends who have fruit this year After the film bag is finished, it is necessary to grasp the fruit tree for the second high phosphorus. 2. Farmers friends who have no fruit on the tree this year due to freezing damage Now that the spring shoots have stopped, it is about to enter the differentiation stage of flower buds. For the next year's production, there will be no fruit in this year's tree. This time, the topdressing of phosphorus should not be less. In the first half of June, the fruit trees must be supplemented with phosphorus. Pulling branches Especially for the park that has no fruit this year, this work is very important. Because there is no fruit in the tree this year, the tree is easy to grow. This is not conducive to the timely stoppage of spring shoots and the normal differentiation of flower buds. method: 1, the main idea of ​​small angle To force the pull, if necessary, open the three saws at the base of the main branch, be sure to pull the angle apart. 2, on the perennial back erect The purpose of the injury from the base or the circumcision at the base is to alleviate the tree's potential to promote flowering. 3. For the orchard that was not carefully trimmed last year. Now it is already closed, and there is no light and no result. The leaves that do not see light have no light and effect. In this case, we have to break the convention this year. For the orchard that is too closed, we can now properly remove a small number of branches to solve the light. (1) For temporary trees You can remove the big branches that affect the light and perform ring stripping or ring cutting on the temporary tree. (2) on the permanent tree Now go to the big branch must be stable, can not go big, now must not be winter shears, can remove some of the weak skills of the base or guilt, as well as the slashing of the slashing mouth, the light on the tree can be adjusted, and Remember that you must not go to the permanent tree, you have to wait until September to go some more.
