September citrus garden forgets drought
To improve the orchard's environmental conditions, there are the following aspects: 1. To protect and use the vegetation around the orchard: When constructing orchards, the vegetation around the orchard should be preserved as much as possible, especially the top of the hill, the natural vegetation in the middle and upper part of the mountain, and the conserved water can improve the air in the orchard. And soil moisture delays the occurrence of drought. 2. The construction of orchard water storage facilities: should be adapted to local conditions, due to the simple construction of small ponds, reservoirs and the use of drainage ditch water storage. 3. Deep-turning and soil reforming: Usually 1 cm thick soil can store about 1 millimeter of water. By changing the soil by deep-turning soil and embedding weeds, improve the ability of the orchard to resist drought. 4. Ground cover: The dry season is covered with straw, mantle, or thatch on the ground and is 10 to 20 cm thick. The coverage ranges from 10 to 15 cm from the trunk to about 50 cm outside the canopy drip line. 5. Grass cultivation on the ground: In the rainy season, weeds are planted in orchards to reduce soil erosion. At the time of the dry season, weeds or grasses are sprayed to cover the ground. 6. Loose soil protection: shallow cultivator, loosen the topsoil, cut off the soil capillary, reduce soil moisture evaporation.
To improve the drought resistance of citrus mainly in the following aspects: 1. Irrigation: During drought, timely irrigation. 2. Moderate pruning and wiping: cut off overlapping branches, branches and branches and branches, and wipe out immature shoots in severe droughts to reduce water transpiration. 3. Select drought-resistant rootstocks: Hilly hills, which are prone to drought, use rootstocks with developed root systems, deep red roots, and limes. 4 Enhance tree vigor: improve the soil, balance fertilization, and appropriately increase potassium, phosphate fertilizer and farm manure.
