Scratching, cut off the capillary in the soil, reduce evaporation, retain moisture, and ensure the soil moisture under the surface. At the same time, scratching can break the surface stratum, which can improve the physical and chemical properties of the soil, increase the permeability of the soil, and thus facilitate the breathing of the roots and contribute to rooting. Therefore, in the management of vegetables in the early stage, we should take scratching as an important management measure. In general, at least two strokes must be made before the seedlings reach the result. If the soil is heavy, the number of strokes will increase. Roots have a habit of being water-based, so controlling water helps to deepen roots and form strong root groups. At the same time, this period of water control is also an important measure to avoid stems and leaves prosperous and "top-heavy". Therefore, after easing the seedlings, management should take control of the water. According to soil conditions, plant growth and weather conditions, determine the water control time. At present, many vegetable farmers use small seedlings to colonize and colonize 2-3 days to plant seedlings. After watering the seedlings, the surface began to scratch and began to scratch. At this time, because the seedlings are smaller, use a hoe or two-toothed hook to draw it lightly. The next day, you will use the hoe to draw a block of soil and push it to loosen. It is important to pay attention to this plan not to move the roots. About 10 days after the emergence of the seedlings, the second time the fish was scratched. The requirements for this demarcation are deep. General depth of 5-6 cm is appropriate, the purpose is to ensure that the surface of the soil under the humidity of 5-6 cm, deep rooting. After 2-3 days, it will be repeated again to increase the permeability of the soil and promote the rapid growth of the root system. SINOCHEM PHARMACEUTICAL CO., LTD , http://www.sinochemnutrition.com
