Three Measures of Autumn Management of Pear Trees
One is autumn basal fat. Application time is from August to September, less nitrogen fertilizer and more potassium fertilizer. The method is to combine the whole garden to plough deep-fed organic fertilizers mainly composed of farmyard manure, apply 50-100 kilograms, and then apply 2 kilograms of fruit tree compound fertilizer and 2-3 borax. Water immediately after application and cover the soil.
The second is to pull branches and branches. Last year's freeze damage, this year pears generally low yield, resulting in excessive growth of nutrients in the tree, the fall should be carried out branches and branches of plastic trees. Mainly remove the long branches, over-close upright branches, cross branches, to thin out the weak branches, pests and branches, root branches. The position and angle of the branches should be reasonable.
The third is to prevent "Little Spring". Pear trees are vulnerable to adverse climate effects. Early leaf fall is prone to the “Little Spring in October†phenomenon, resulting in flowering affecting leap year results. The main measures are the prevention and treatment of pests and diseases such as pear scab, pear hibiscus, and pears and weevil from August to September; pay attention to irrigation during droughts to prevent the soil from becoming too dry.
