Watermelon planting and topdressing method

Abstract

The invention relates to a watermelon planting and topdressing method. The percentages of fertilizers applied by a distribution ratio are as follows: 60% of a phosphatic fertilizer, 20% of a potassium fertilizer and 10% of a nitrogen fertilizer, and the fertilizers are applied in a ditch in front of plants as base fertilizers. After the plants survive, the fertilizers are spot-applied at parts 10cm from the plants for the first time, and the fertilizer applying quantity is 10% of the total fertilizer quantity. When the plants grow five to six leaves, the fertilizers are applied in a shallow ditch formed among the plants for a second time, and the fertilizer applying quantity is that the ratio of N to P205 to K20 is 20% to 20% to 30%. At the period that female flowers blossom, the fertilizers are applied on the two sides of a furrow into two strips for a third time, and the fertilizer applying quantity is that the ratio of N to P205 to K20 is 20% to 0% to 30%. When young fruits are as large as a fist, the fertilizer is applied into ditches formed in the two sides of the furrow for a fourth time, and the fertilizer applying quantity is the rest 20% of the nitrogen fertilizer. If the field is of sand soil, when the fruits grow larger, 0.4% of urea solution is sprayed on the leaf surfaces once every week and continuously sprayed for twice to three times. Through scientific fertilizer application, the watermelon planting and topdressing method reduces fertilizer wastes and soil pollution, ensures and improves watermelon quality, and obtains certain economical and social benefits.
