It is currently in the summer, this time is also the radish sowing period, then you know how to make high-yield summer radish? The following small series will share with you, summer radish high-yield cultivation soil selection, fertilization and field management skills, I hope to help you plant.
1, variety selection
The summer radish cultivated in the off-season should be selected from high-quality varieties with strong heat resistance and strong disease resistance. Such as Xia Changbai No. 2, Dongfang Huimei, Xia Meiqiang Early Health No. 3, Xia Kang 40 days and other varieties.
2, soil selection
For radish-growing land, it is advisable to choose sandy loam soil with rich humus, deep soil layer and good drainage. The front hoe is better for fertilization with less fertilization, less fertilizer, and a lot of fertilizer left in the soil, such as early kidney beans and cucumber.
3, base fertilizer
Deep ploughing and ploughing, combined with deep ploughing before sowing, decommissioning fully decomposed organic fertilizer, ash, superphosphate, ploughed into the soil, dried and then ploughed into the soil, or 2,000 kg of organic fertilizer, 20 kg or more of compound fertilizer, once Apply enough base fertilizer, and then look at the seedlings and topdressing.
4, sowing
The suitable sowing period of summer radish is that the Huanghuaihai area is generally in the middle of April, sowing seeds early, and the disease is heavy when the radish is inflated. Ridge cultivation, the ridge distance is 80 cm, the height is 15-20 cm, and the distance between the ridges is 20 cm × (20-25) cm, more than 26,000 per acre.
Generally 2 capsules per hole, 5 to 7 leaves when seedlings are timely, when planting must use the soil (such as trichlorfon, phoxim, etc.) seed dressing or pesticide dressing to prevent underground pests, while applying 40 per acre 1.5 kg of pentachloronitrobenzene to prevent fungal diseases.
After the sowing, in addition to the cover soil, it should be covered to maintain moisture, ensure that the seedlings are quickly and tidy, and prevent the rainwater from binding the soil, hindering the emergence of the seedlings. The cover can be covered with wheat straw, ash fertilizer, etc. The thickness of the cover soil after sowing is about 2 cm. More than 3 cm, covered with a sunshade net to keep the field wet without stains.
5, field management
5.1, watering
After the sowing, check the lack of replanting in time, and the summer is hot, the sunshine is strong, the field is generally dry, and special attention should be paid to proper watering. In the germination period, the water should be fully watered when planting, the soil water content should be above 80%; in the seedling stage, the soil water content should be 60%, the principle of less pouring and pouring should be mastered; the leaf growth period (from whitening to whitening) Off-shoulder), moderate irrigation, but not too much water; root growth period, special attention should be paid to adequate and uniform water supply, soil moisture 70%～80%, air humidity 80%～90%, if the water supply is uneven, it is easy Cause cracking. Watering the summer radish should avoid watering at noon, preferably watering in the evening.
5.2, top dressing
In principle, the topdressing period is mainly applied before the radish expansion period. The application of nitrogen fertilizer can be used for manure and chemical fertilizer. If the concentration of excreta is too large, the roots will be hardened. Generally, water should be applied during watering, human excrement and nitrogen fertilizer. Applying too late will cause the fleshy roots to become black, the quality is deteriorated, or it is broken, or bitter.
6, harvesting
The growth period is about 50 days, and it can be listed in batches.
The cultivation of summer radish wants to obtain high yield, mainly in the selection of varieties, followed by land selection and fertilization. The above is a field management method for high-yield cultivation of summer radish. Parents who want to plant can learn from it.
