Field management of open field radish in spring

When the temperature rises in spring, vegetables can be sown in the open field without any protective facilities, while spring radish is a type of radish harvested in early spring and summer, which is a kind of vegetable to solve the off-season of vegetable supply in early summer, and its growth period is relatively short. so how to manage it in the field? Let's get to know it with the editor.

1. The seedlings are fixed

After the emergence of radish seedlings, there should be time for seedlings, so as not to grow, inter-seedlings and fixed seedlings to achieve early uniform seedlings, multiple seedlings, late fixed seedlings, select strong seedlings, remove poor, weak, disease, miscellaneous seedlings. In the seedling stage, it is usually 2-3 times. For the first time, when the cotyledons are unfolded, the first piece is carried out when the heart is exposed, it is only necessary to open the seedlings; the second time is when there are 2-3 real leaves, 2-3 plants are left in each hole, and the strip sowing can be carried out according to the plant distance of 10-12 cm. Seedling setting should be carried out in time when there are 5-6 true leaves. Generally, the plant spacing of large varieties should be controlled at 25-30 cm and that of medium-sized varieties should be controlled at 25-25 cm.

2. Ploughing and weeding

Radish needs loose and breathable soil for its growth, so it is necessary to plough the soil in time, especially in spring radish seedling stage, generally 2-3 times from seedling stage to ridge closure, and the depth of intertillage should be determined according to the growth and development of the plant. The first time ploughing should be shallow, the first time it should be deepened, but do not touch the root system, and cultivate the soil with intertillage before the third ridge closure.

3. Watering

Spring radish seedlings should be watered as little or late as possible, while summer radish and autumn radish should be watered in time if the soil is dry to ensure that the seeds have enough water to germinate. Before the root system at the seedling stage, the amount of water absorbed is less, and the principle of frequent irrigation of small water should be harvested to reduce the ground temperature to prevent the occurrence of virus diseases. There are more Rain Water in spring and summer, which can easily cause stagnant water to soak the roots, so we should pay attention to drainage and waterlogging prevention.

4. Topdressing

According to the law of the need for nutrient elements in the growing period of radish, the amount of topdressing should grasp the principle of "light, heavy and light". In the case of sufficient base fertilizer, the first topdressing can be carried out when the seedlings grow two true leaves before the seedlings are fixed. Generally, 10-15 kg of compound fertilizer or 50-100 kg of mature cake fertilizer is applied per mu, ditched on both sides of the plant and covered with soil after fertilization. In the shoulder-exposed and fleshy root expansion period, all kinds of topdressing were applied once, urea 15-20 kg per mu, potassium dihydrogen phosphate 10 kg per mu, and watering once after each fertilization to promote fertilizer decomposition.
