The concrete measures for cultivation of depressions in the Pingzhang include the following: first, the land shall be planted into a flat stubble, the plants shall be cultivated, and a shallow ditch shall be formed in the middle of the raft. The original ravine shall be divided into two, and the shallow ravine shall be formed in two. In the middle of Pingshuo, it is called "the flat ditch dark ditch." The formation of flat ravines usually takes 2 times of earth. The first soil was carried out after the seedlings were raised; the second soil was determined by the cultivated crops. The vegetables needed to be racked were generally placed in front of the racks, and the dwarf vegetables were arranged after the second watering. In the process of earth-cultivation, the principle of burying the second true leaf is as follows. In the end, the depth of the shallow groove is generally 7-10 cm, the width is 20-25 cm, and the width is 5-0 cm.
Its advantages are as follows:
Water-saving vegetables are easy to irrigate when irrigation needs to be carried out in shallow ditch when irrigating, the water flow is fast, and the ditch is in the middle of the two small plows, which are close to the roots of the plants, easy to reach the roots of the plants, overcome the slow flow of water, large dosage Shortcomings. At the same time, it avoids the inadequacies of waterlogging and plant water-absorption difficulties such as sorghum and ridge.
Easy to drain and prevent flooding This type of squat has the characteristics of high enthalpy. When it is rainy, it can quickly drain water from the ditch and prevent the occurrence of scurvy.
Conveniently, the top-dressing topdressing soil can be combined with topdressing after the plant is seedlings; if it is weak, it can be top dressing and then soil. This method can prevent damage to the root system during topdressing and prevent loss of fertilizer and water.
To promote the development of root system and to prevent the lodging of flat dark ditch is the formation of two cultivating soil, the rhizosphere soil is looser, the porosity is increased, the oxygen content in the soil is increased, the temperature condition is improved, and the root growth of the vegetable effect is accelerated, after the soil is cultivated, the plants are firm Increased degree can effectively prevent lodging.
It is easy to manage in the field, easy to pick water when it is flat, easy to collapse after watering, easy to collapse after watering, after ridges are watered, the ditch is very heavy, and timely harvesting in field management is inconvenient. Because of the watering in the trenches, the water level of the flat sulcus cultivation is easy to control, and the embankment is intact after being cultivated, which facilitates field management and harvesting.
