The yield and fruit size of chestnut seedlings are related to the amount of fertilizer and irrigation. Excess water will saturate the soil for a long time. Due to lack of oxygen, the roots of plants will rot, mildew and even die. Too much fertilizer or too high fertilizer concentration can easily lead to scorched, withered and dead roots of plants. In particular, the root absorption capacity of new potted plants is weak, and the main nutrients and water consumed at this time are easy to burn the fertilizer of tender roots.
In spring, the temperature difference between cold and hot is large, and chestnut seedlings move out of the shed prematurely. Chestnut seedlings cannot adapt to the rapidly changing weather conditions outside, and are prone to death. In addition, once chestnut seedlings grow new leaves, they will be immediately exposed to the sun, which will accelerate the evaporation of leaf water, dehydrate the plant and cause death. Chestnut seedlings generally need to be watered 3-4 times in the whole growth period, that is, after crown buckling and before germination. The amount of water is slightly larger, so that the water is immersed in the soil layer of about 50cm, which promotes the germination, flowering and leaf development of chestnut, increases the leaf area, and improves the fruit setting rate. After flowering, appropriate secondary irrigation is the main method to promote the growth of young fruits and new shoots. The third irrigation before fruit ripening can promote fruit development, increase fruit size and improve fruit quality, because the fruit enters the rapid growth period about a month before harvest. However, the amount of watering should not be too large, otherwise it will easily lead to fruit falling, cracking and quality decline before harvest. After fruit harvest, the fourth Topdressing and watering will promote the accelerated growth of new shoots of chestnut seedlings and the differentiation of flower buds in the open field. In the future, irrigation can be carried out according to specific conditions such as weather, soil and tree vitality. Each irrigation should be combined with Topdressing and timely weeding.
