Irrigation and soil moisture Conservation in Chestnut Orchard in Spring

After the chestnut sprouts, the new shoots quickly turn into rapid growth, and branches, leaves and inflorescences appear one after another. the composition and development of various organs need not only water, but also water for nutrient absorption and transport. Therefore, chestnut farmers regard early spring and pre-flowering irrigation as a critical period of production. In addition, according to the experiment, about 15 days before harvest, irrigation in dry days can increase production by 10% to 20%. Practice has proved that spring irrigation can promote the formation of female flowers, benefit the growth of branches, and play a good role in increasing the yield of the same year. Drought resistance and soil moisture conservation: chestnuts in China are mostly planted in mountainous and hilly areas. Generally, the soil layer is thin, the performance of soil moisture conservation is low, and irrigation is difficult. Therefore, attention should be paid to drought resistance and soil moisture conservation. Grass mulching can loosen the soil, reduce the soil temperature, maintain humidity, and is beneficial to the growth and absorption of roots. The improvement of underground conditions directly affects the aboveground growth status, which is beneficial to fruit setting, reducing empty involucre, increasing grain weight and increasing yield. The method of preserving soil moisture is simple and easy, and local materials can be used. Every year, tree plates are planed before the rainy season, Weir repair plates are built, soil is preserved and water is stored, and tree plates are covered with fallen leaves of weeds in the mountain field, as well as rubbish and stones.
