Recently, some fields with early-maturing melons, early corn, and early-early soybeans were harvested, and Hou Tian was idle. They saw a bit of a waste of land resources. In order not to miss farming, it is recommended that these unused fields be planted with hot summer radish. First, the growth period of the summer heat radish is very short. It takes about 50 days from the emergence to the harvest. Second, it can fill the gap in the supply of radish in the autumn vegetable market, and the price is good.
At present, we can start from three aspects and achieve quality and high yield of summer hot radish.
First, grab a spot to optimize fertilization. Radish requires high soil fertility for planting field crops. Attention should be paid to preventing partial application of nitrogenous fertilizer and excessive growth of leaves on the ground, resulting in hollow appearance of fleshy roots and affecting the quality of fleshy roots. When fertilizing, in addition to nitrogen fertilizers, phosphorus and potassium fertilizers must be applied. In the early growth stage of radish, more nitrogen is absorbed, but it enters the period of meat root swelling, and the demand for phosphorus and potassium fertilizers increases obviously. In particular, the need for potassium fertilizer is more urgent. At the same time, the fertilization experience of high-yield radish is that the base fertilizer accounts for about 70% of the total amount of fertilizer, and topdressing only accounts for about 30%. The most urgent task now is to grab the sensation, finely prepare the soil, and apply basic fertilizer. Each acre should be applied to produce about 1500 kilograms of high-quality fertilizer produced by the farmer. Avoid using fertilizers that have not yet been decomposed, because the fertilizer can easily hurt the roots after heating and cause the fleshy root to rot or rot. At the same time, with the application of 15 kg of phosphate fertilizer, a high content of 10 kg of potassium or 100 kg of plant ash. While paying attention to the basic fertilizer, we should not ignore the top dressing. The root of the fleshy roots grows. At least we must topdress 5 kg of urea and 5 kg of potassium sulfate. During the growth of the summer hot radish, it often encounters heavy rain, and it is necessary to narrow the deep trench to facilitate drainage. Cab width 2~2.5 meters, ditch width 0.4~0.5 meters, depth 0.3 meters.
Second, choose heat-resistant radish varieties. Through production practice, it has been repeatedly proved that the heat-resistant radish varieties include Xia Kang 40, Short Leaves 13, Short Leaves 13-6, Ma Er Zao, Locomotive, and Bright White. These radish varieties generally have tender meat, high yield, and no odor. The growth period is only 40 to 60 days.
Third, diligent in the management of pest prevention. Premature radishes are mostly sowing, one must be seedlings with time and seedlings, and about 6 leaves should be suitable for seedlings; secondly, weeding and weeding should be used to promote good root development; third, we must use shallow soil to prevent exposed roots from lodging and bending. Fourth, we must do well. Irrigation and drainage to prevent hot and dry produce spicy taste; Fifth, prevention and control of diseases and pests, focus on the prevention and control of viral diseases, black rot, downy mildew, and rapeseed meal, rapeseed meal, cabbage caterpillar, diamondback moth and other pests.
