Under normal circumstances of water management, areas with annual precipitation between 600 and 800 mm and uniform precipitation distribution can meet the needs of walnut growth and development. In summer, there is often insufficient precipitation or uneven distribution, resulting in long-term or periodic droughts. Therefore, water should be supplemented by irrigation to meet the needs of walnut growth and development. However, the time and frequency of irrigation should be determined according to the specific situation, and should generally be combined with fertilization. Soil management intercropping. Newly planted young trees can be intercropped to improve land utilization. Intercropping is mainly based on low-stalk crops such as peanuts, millet, beans, and Chinese herbal medicines, and the cultivation of high-stalk crops such as corn is strictly prohibited. During intercropping, a full 1.5-meter nutrients should be kept to ensure the normal growth of walnut seedlings. Loose the weeds. Weeds not only compete with walnut trees for water and fertilizer, but also easily cause diseases and insects. Walnut trees generally need to be weeded 3 to 4 times in order to obtain high and stable yield and high quality. In addition, cultivating the soil can increase soil permeability and moisture retention capacity and prevent soil compaction.

Scientific management of soil, fertilizer and water for walnut in summer
Fertilizer management At this time, topdressing is mainly based on quick-acting fertilizers. During the fruit expansion period from May to June, 2 to 3 year-old young trees apply 50g of urea per plant and 100-150g of compound fertilizer. 100 ～ 150g, compound fertilizer 100 ～ 200g. Radial, cavernous, and ditch-shaped fertilization can be used, with a depth of about 30 cm, and soil and irrigation after application. It can also spray foliar fertilizer 1 or 2 times at the same time. Commonly used fertilizer types and concentrations are: urea 0.3% ~ 0.5%, superphosphate 0.5% ~ 1.0%, potassium sulfate 0.2% ~ 0.3%. Fertilization is generally carried out before 10 am or after 4 pm, and it is not suitable to spray fertilizer in rainy or windy weather.
