Abstract

The invention discloses a wax gourd fertilizing method for reducing nitrogen and increasing yield. The method comprises the following steps: when ploughing a land, spreading the decomposed farmyard organic fertilizer and bagasse activated carbon, wherein the decomposed farmyard organic fertilizer spread on each mu contains 12kg of pure nitrogen which accounts for 50% of the total amount of the spread pure nitrogen; when ridging and bedding, spreading ENTEC slow-release fertilizer on each mu, wherein the pure nitrogen content is 7.2kg, accounting for 30% of the total amount of the spread pure nitrogen; transplanting the wax gourd grafted seedling, wherein the wax gourd grafted seedling is obtained by taking the Haizhan No.1 pumpkin as a stock and the Tiezhu black wax gourd as a scion and soaking the root system in a gibberellin solution after grafting; performing topdressing for 6 times with an under-film dropper in the vine extending period, the flowering period, the fruit setting period and the fruit swelling period of wax gourd, wherein the amount of the spread pure nitrogen is 4.0kg, accounting for 20% of the total amount of the spread pure nitrogen. By adopting the fertilizingmethod disclosed by the invention, the yield reaches 9,000kg / mu and can be increased by 34.03%; the dosage of nitrogen fertilizer can be reduced by 5-10kg per mu, the absorption and utilization efficiency of the nitrogen fertilizer reaches 40.61%, and the quality of the wax gourd fruit is obviously improved.

Description

technical field [0001] The invention relates to agricultural planting technology, in particular to a method for fertilizing wax gourds by reducing nitrogen and increasing production. Background technique [0002] Winter melon is an important supply variety of melons and vegetables transported northward in winter in Hainan Province. Its economic benefits are remarkable, and it is an important means for local farmers to get rid of poverty and become rich. Currently, the annual planting area of ​​winter melon reaches 8,000 hm 2 Above, the yield of wax gourd per mu can reach more than 75,000kg. Nitrogen fertilizer is the main production factor of wax gourd. Compared with other macronutrients, it has a greater impact on the yield of wax gourd. In order to pursue high yields, farmers often apply excessive nitrogen fertilizers and unreasonable fertilization in production, resulting in serious imbalances in nitrogen, phosphorus, and potassium nutrients, which not only cause waste of...
