What management techniques should be paid attention to if you want to plant horseshoe seedlings with high yield?
Kakashi should be transplanted as far as possible, and the planting time should be carried out in rainy days or when the sun is not obvious at dusk to prevent seedlings from burning. When transplanting horseshoe, we should do six things: no weak seedlings, no injured seedlings, no "boring seedlings", no "clenched seedlings", no pin marks and hard mud bumps, no "wind-resting seedlings" and "overnight seedlings". Seedlings should be inserted directly, and the row spacing should be straight. Manage water resources scientifically and reasonably. Water chestnut belongs to aquatic crops, and all the growth links are inseparable from water, otherwise plants cannot grow and develop. However, irrigation must be effective. After transplanting horseshoe, due to root injury and weak water absorption, it needs moderate irrigation to protect seedlings, and then persevere in shallow water.
Ensure that the back water can't see the front water, keep the horseshoe field dry and wet, and avoid long-term deep water flooding. After the horseshoe of the second shore field is perfected, it should immediately fall into the water to dry the field, which is convenient for harrowing and digging. During the growth and development, the flower soil should always be kept moist, and water should be sprinkled on the leaves and roads at ordinary times to increase the relative humidity of the air. Topdressing every half month 1 time. Phosphorus and potassium fertilizer should be applied before flowering to control the growth and development of leaves and stems, promote the promotion of flowers and ensure the quality of flowers. When applying fertilizer, it is forbidden to inject liquid fertilizer into leaf stems to prevent rot, and spray new high-fat films to stabilize the soil and keep water.
If there are too many leaves in the process of growth and development, you can remove a few yellow leaves outside to facilitate the pulling out of the flower stalk. February-May is the flowering period. Spraying Petal Zhuangdiling in bud stage can promote the stamens to be strong, the petals to be thick, the color to be bright, the fragrance to be rich and the flowering period to be prolonged. The big ball is in full bloom, and the ball can raise seedlings. After the hot weather in the middle and late May, the plants gradually turn yellow, so watering should be stopped gradually, and proper shading should be done to prevent water accumulation. Potted plants should be moved to a naturally ventilated and semi-shady place, so that the pots can be placed on the side to avoid precipitation, so as to keep them dry and promote their dormancy. After all the leaves turn yellow, you can take out the bulbs, dry them and store them in a naturally ventilated and cool place. Before planting in autumn, cut off the old part at the bottom of the bulb and replant it.
