Embodiment

[0044] 1. Preparation of Slow Release Fertilizer

[0045] 1) Quantitatively weigh 340 kg of granular urea-formaldehyde; 140 kg of granular superphosphate; 100 kg of granular diammonium phosphate; and 420 kg of granular potassium sulfate.

[0046] 2) Mix well according to the above ratio, which is the slow-release formula fertilizer for watermelon long-season cultivation; the particle size of the fertilizer is 3-4mm, and the nutrient release period is up to 100 days.

[0047] The special slow-release fertilizer for watermelon obtained by mixing according to the above ratio contains about a large amount of nutrients (N+P 2 o 5 +K 2 O) 42%, Nitrogen (N) 15%, Phosphorus (P 2 o 5 ) 6%, Potassium (K 2 O) 21%; ratio of three elements (N:P 2 o 5 :K 2 O) is 2.5:1:3.5, of which slow-release nitrogen accounts for 90% of the total nitrogen fertilizer, contains calcium (Ca) 2.8%, sulfur (S) 7.5%, and trace elements (Fe, Mn, Zn, B, etc.) content About 1%.

Abstract

The invention relates to the field of crop planting, and specifically relates to a watermelon long-season cultivation slow-release formulated fertilizer and applications thereof for special fertilizers for watermelon cultivation. The watermelon long-season cultivation slow-release formulated fertilizer comprises the following components in percentage by mass: 30-35% of urea formaldehyde, 12-15% of calcium superphosphate, 8-10% of diammonium phosphate, and 40-45% of potassium sulphate. In the formulated fertilizer disclosed by the invention, a large number of nutrient elements and medium trace elements are combined, and long-acting nutrients and quick-acting nutrients are combined, so that the components of the fertilizer are associated with the watermelon fertilizer absorption law, and the release of fertilizer nutrients is consistent with that in the watermelon fertilizer-required peak; and finally, the watermelon long-season cultivation slow-release formulated fertilizer which is reasonable in formula, comprehensive in nutrients and lasting in fertilizer effect, enables the watermelon cultivation process to be time-saving and labor-saving and enables the cultivation results to achieve an effect of increasing both production and income is obtained.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a slow-release formula fertilizer for watermelon long-season cultivation and application thereof. Background technique [0002] Watermelon belongs to Cucurbitaceae, an annual vine herb with crisp and tender flesh, sweet and juicy, rich in mineral salts and multivitamins. The growth cycle of watermelon can be roughly divided into six stages, seedling stage, vine extension stage, fruiting stage, fruit expansion stage, fleshy stage, and maturity stage. The planting time and planting mode are different in different regions. The Shanghai area can be divided into winter and winter. Spring stubble cultivation (transplanted in January, harvested in April), autumn stubble cultivation (transplanted in August, harvested in November), long-season cultivation (transplanted in February, 4 batches of continuous picking of melons from April to October), According to the cultivation management mode,...
