When is the prickly thorn pruned

Generally, it can be pruned scientifically and reasonably in spring, summer and winter. Pruning in spring and summer is to promote the growth of branches and leaves of Nitraria japonica. The over dense branches and leaves can be thinned to improve the light conditions in the crown. At the same time, cut off the weak buds and dead branches on the plant to save nutrients. Winter pruning is mainly to shorten the branches and leaves, feed the growth of plants in the coming year and preserve nutrients. At the same time, winter shearing can also prevent pests from perching on dead branches. 1、 When to prune Nitraria pinnatifida? Generally speaking, its branches and leaves should be pruned when Nitraria pinnatifida grows vigorously and after harvest. In the growth period of branches and leaves, thinning and topping should be carried out in time to promote the growth of lateral branches of Nitraria japonica. When pruning, it is necessary to retain full and vigorous flower buds, branches and leaves, and remove some weak branches that develop slowly and waste nutrients. The weight of pruning needs to be adjusted according to the actual growth year and growth trend of Nitraria. 2、 How to plant Nitraria bungeana 1. Seed treatment: after picking the fully mature Nitraria bungeana, the pulp of Nitraria bungeana can be removed with a beater, leaving full and pest free seeds. Then wash the impurities and sugar on the seeds with clean water, dry them and store them in a breathable environment. Before sowing, the seeds need to be disinfected with potassium permanganate solution.

2. Sowing and seedling raising: sowing prickly thorn can choose three forms: sowing, drill sowing and hole sowing, among which drill sowing has higher efficiency and seedling emergence rate. After the seeds are sown in the soil, they should be watered every two days until the seedlings emerge. When the seedling height reaches 20cm, the seedlings can be transplanted into the field, so that the seedlings have more growth space. (BaiCiGuoShenMeShiHouXiuJian)
