Embodiment 1
[0048] The cultivation method for improving single melon weight and sugar content of honeydew melon comprises the following steps:
[0049] Step (1), soil preparation
[0050] Deep plowing 30 cm, fine harrowing, fertilization, ridge mulching. Two drip irrigation belts are laid on the ridge, covered with green film, and silver reflective film between the ridges.
[0051] Step (2), raising seedlings
[0052] Sowing period: Sow seeds from October 1st to 5th. Sow seeds in batches. Use plastic seedling trays to grow seedlings with a moist substrate. The size of the seedling holes is 2cm×2cm×2.5cm. Keep the substrate moist, keep the humidity at 60-70%, and control the temperature at 25°C-30°C. Generally, germination will take 2-5 days germination.
[0053] Step (3), transplanting
[0054] The melon seedlings can be transplanted when they grow to 2 bud leaves on the seedling tray. Select melon seedlings with good growth, no disease, green seedling color, uniform bud and leaf s...
Embodiment 2
[0074] In the present embodiment, drip irrigation of potassium fertilizer 4 times until honeydew melon ripening harvests from the fruit expansion period, each drip irrigation uses potassium sulfate (K 2 (0%=50%) 1.2kg, potassium malate 0.5kg, potassium citrate 0.5kg. All the other are identical with embodiment 1.
[0075] The fertilization method in the control experiment was:
[0076] When transplanting, each honeydew melon was applied with "Jinyu" brand 3F high-efficiency humic acid organic fertilizer 4.0g, ternary compound fertilizer (N:P 2 o 5 :K 2 O=10%:10%:25%) 2g. Mix pond dry application.
[0077] 15 days after transplanting, start to apply topdressing fertilizer with water, and the application rate is 4.5kg / mu of nitrogen and potassium fertilizer. Treat 20 melons and pour them at one time. Each melon is 1.5kg of fertilizer solution. The fertilizer solution is 90.00g of nitrogen and potassium fertilizer mixed with 30kg of water.
[0078] 1-2 days after the flowe...

Abstract
The invention relates to a cultivation method for increasing the single melon weight and sugar content of honeydew melons. The method comprises the embodiment that during transplantation, 4.0-5.0 g ofefficient humic acid organic fertilizer and 2-3 g of nitrogen, phosphorus and potassium composite fertilizer are applied to each honeydew melon; 15 days after transplantation, drip irrigation of nitrogen-potassium fertilizer starts to be conducted, and 1-1.5 kg of nitrogen-potassium fertilizer is applied per mu each time; drip irrigation fertilization is conducted once every week, and drip irrigation fertilization is conducted three times in total, wherein the fertilizer concentration is 0.1-0.2%; 1-2 days after blossom falls, nitrogen, phosphorus and potassium composite fertilizer starts tobe applied, 2.0-2.4 kg of nitrogen, phosphorus and potassium composite fertilizer is applied per mu every time, drip irrigation fertilization is conducted once every week, and drip irrigation fertilization is conducted three times in total, wherein the fertilizer concentration is 0.3-0.5%; from the beginning of the fruit swelling period, drip irrigation of potassium fertilizer is conducted 4-5 times till the honeydew melons ripen and are harvested, wherein the potassium fertilizer is composed of 1.2 kg / mu water-soluble potassium sulfate, 0.5-1 kg / mu dipotassium malate and 0.5-1 kg / mu potassiumcitrate, and the fertilizer concentration is 0.4-0.5%. By adopting the cultivation method, the average single melon weight is increased by 0.33-0.63 kg, and the average yield is increased by 22.75-43.44%; the average sugar content is increased by 1.7-2.0% compared with a contrast.
Description
technical field [0001] The invention relates to a cultivation method, in particular to a cultivation method for increasing the weight and sugar content of a honeydew melon, belonging to the field of cultivation. [0002] technical background [0003] Shizuoka Prefecture is located in the central part of Japan, between Tokyo and Osaka. facing the Pacific Ocean. It is 155 kilometers long from east to west and 118 kilometers wide from north to south. Shizuoka Prefecture has an average annual temperature of 17.5°C and an annual rainfall of 3,391.5 mm. Except for the northern mountainous areas, Shizuoka Prefecture has a mild maritime climate, and it rarely snows in winter in the plains. Spring is warm; summer is the first half of the rainy season, and the second half is sunny and high temperature; autumn is cool and cloudless; winter is dry and sunny, which belongs to the region with four distinct seasons. Due to Shizuoka's special geographical location and climatic conditions,...
