The construction of a water kiln underground in Taoyuan has high water-saving and energy-saving benefits. Now its cultivation techniques are described as follows: 1 Construction time and methods of kiln construction 1.1 Time for building pits The best time to build cellars is from late February to March every spring. In the middle of the year, it will be conducted together with the peach tree spring fertilization. 1.2 Dig a cylindrical cellar along the peach tree projection, dig 4-6 cylindrical kilns around each plant, with a diameter of 50 cm and a depth of 40 cm. 1.3 Twisting crop straw bundles Combine corn straw, rice straw, or wheat straw with straw ropes or hemp straws into bundles of cylindrical straw. The better, the better, the bundles are 30 cm high and 30 cm in diameter. 1.4 The buried straw stands upright in the pit, then fills the soil, fills the topsoil to the bottom, and fills the bottom soil to the top. Straw bales are buried on the top of the bale so that the top floor is trimmed 2-4 cm lower than the surrounding ground so that the rain can be stored in the pit. 2 When fertilizer and water management topdressing and watering, the top soil of the small cellar is shoveled out with a shovel, and the fertilizer is sprinkled on it. When the water is poured, the fertilizer dissolves in the water and enters the water cellar with the water, penetrates into the surrounding area, and is absorbed by the peach roots. . Excess moisture and nutrients are temporarily stored by crop straws. As time goes by, it is released little by little and is used by peach trees. The roots of peach trees also grow and elongate in water cellars. Due to sufficient water and fertilizer, the root volume increases dramatically, laying a solid foundation for increasing production. After summer and autumn, the crop straw is rotted and the water kiln filling material is sinking. It can be filled with excreta and weeds. In the spring of the following year, digging pits again along the peach tree projection, rebuilding the water cellar, and so on. 3 Benefits of building a water cellar 3.1 Water-saving and water-saving energy-saving crops Straw absorbs enough water to prevent evaporation and has good water storage. There is also dissolved fertilizer, moisture, and nutrients for the use of peaches for a longer period of time. 3.2 The soil can be changed year by year. The crop straw in the water cellar will decay after summer and increase the humus of the soil. The soil is loose and has good permeability. 3.3 Taoyuan, which does not build water cellar in the roots of less-damaged peach trees, has a certain degree of damage to the roots of the peach tree each time it is pitted or trenched. The construction of cellar pits only hurts once the pit is digging and there is no harm afterwards. 3.4 favorable for the growth of the tree water hole pit storage water for the peach root system to create a suitable environment, so that normal growth of peach. Compared with the dry land cultivating gardens, the peach tree shoots in the water cellar have a large amount of growth (especially the spring shoots are thick and long), and the proportion of effective short shoots in the first and second categories is high, and the leaves are large and thick, which is beneficial to the length of the peach fruit. The quality of peach.
