How to manage planting summer radish?
How to manage planting summer radish? Please introduce the management methods for planting over-summer radish can refer to the following methods: 1. Interseedling, fixed seedling: after the seedling is unearthed, the first seedling is carried out when the cotyledons unfold, and the second seedling is carried out after growing 3-4 true leaves. When the seedling has 5-6 leaves and the fleshy root of radish breaks its belly, only one robust seedling is retained in each hole. 2. Intermediate ploughing and weeding: combine the seedlings with shallow and then deep ploughing and hoe, and at the same time cultivate the soil in the furrow on the border surface to prevent seedling inversion. 3. Timely irrigation: the temperature in summer is high and the water evaporates quickly, so it should be watered reasonably according to the soil moisture and the characteristics of each growth period of radish. At the seedling stage, the seedlings have shallow roots and small water requirements, so it is necessary to grasp the principle of "less watering and watering frequently"; in the peak leaf growth period, it is necessary to grasp the principle of "proper watering" and not to water too much; during the fleshy root expansion period, it is necessary to grasp the principle of "adequate and uniform water supply" and keep the soil moisture at 70% and 80%. Note: summer carrots are not allowed to be watered at noon, preferably in the evening. 4. Fertilizer application: urea 8-12 kg per mu after seedling setting and watering to promote leaf growth; in the early stage of fleshy root expansion, 15-20 kg urea or ammonium sulfate per mu and 10-15 kg potassium sulfate per mu can be applied with water. In addition, if combined with root topdressing and foliar spraying for 2-3 times, it will effectively promote the expansion of fleshy roots. 5. Pest control: the temperature is high in summer and there are many pests, such as cabbage insect, aphid, Plutella xylostella, yellow striped armyworm, etc. Insecticides such as Lesbon, imidacloprid, Yitaibao, BT EC can be selected to control black rot, soft rot, virus disease and other diseases.
