A Complete Guide to the Latest Fertilization Methods for Autumn Radishes
Radish is a main vegetable in autumn and winter. In early autumn, this is generally the main planting period for radishes. When planting radishes in autumn, we need to provide them with sufficient nutrients. To ensure their yield and quality, the fertilization work for autumn radishes is especially important, so we must fertilize in time in autumn. So how should autumn radishes be fertilized? Below, the editor brings you the fertilization methods for autumn radishes. Let's take a look!
1. Apply sufficient base fertilizer
When planting autumn radishes, the application of base fertilizer is very critical. Applying sufficient base fertilizer is the main measure to ensure high radish yields. When applying base fertilizer, we should choose suitable types and amounts according to the soil and the planted variety. For example, when planting autumn radishes in the Yangtze River Basin, farmyard manure is generally used as the base fertilizer. However, base fertilizer alone should not be applied, otherwise autumn radishes are prone to excessive vegetative growth and their quality will not be very good. Therefore, we should also pay attention to combining it with appropriate amounts of phosphorus and potassium fertilizers, barnyard manure, and other fertilizers. Before sowing, phosphate fertilizer can also be applied in holes. Applying an appropriate amount of superphosphate per mu can effectively increase the yield of autumn radishes.
2. Fertilization methods
Generally, about 2800 kg of barnyard manure should be applied per mu as base fertilizer, together with 50 kg of plant ash and about 30 kg of superphosphate. During land preparation, mix it into the soil, then apply about 3000 kg of farmyard manure. Rake the soil level and make beds to promote the growth of autumn radish seedlings, increase the rate of strong seedlings, and enhance the growth of the fleshy roots of autumn radishes. When applying base fertilizer, be sure that the farmyard manure is fully decomposed to avoid burning the main roots of the seedlings. While ensuring the nutritional growth of the seedlings, it is also necessary to avoid fertilizer damage.
3. Reasonable topdressing
When topdressing, we should follow the fertilizer requirement pattern of autumn radishes, and in terms of topdressing amount, follow the principle of heavy-light-heavy. When the autumn radish seedlings grow two true leaves, carry out the first topdressing, mainly with dilute human feces and urine. Then, during the second thinning of seedlings, carry out the second topdressing, and this time combine it with an appropriate amount of potassium sulfate. Then carry out the third topdressing when the autumn radish plants grow to the small-to-medium size. At this time, the fleshy roots of the radishes will expand rapidly, and after that no further topdressing is needed. However, if they are large autumn radishes, their growth period is relatively long, so when the radishes begin to shoulder, we should apply an appropriate amount of potassium fertilizer again, which is very beneficial for increasing yield.
The above is a brief introduction to the fertilization methods for autumn radishes. When planting autumn radishes, fertilization is very critical. It directly affects the growth of autumn radishes and is closely related to the yield and quality of the radishes, so everyone must pay close attention. That is all for today's introduction.
