Embodiment Construction

[0008] The loofah is selected from high-yield and early-maturing varieties such as six-leaf fragrant loofah, and the seeds are sown after soaking and accelerating germination. The seedlings are about 40 days old and the melon seedlings have 4 leaves and 1 heart. Plant them with a large row spacing of 80 cm, a small row spacing of 50 cm, and a plant spacing of 35 cm. For transplanting field, apply 2000 kg of decomposed chicken manure, 50 kg of 25% ternary compound fertilizer, and 15 kg of urea per mu. Before the end of March, antifreeze and heat preservation should be the main focus, and the temperature of the shed should be kept at 25-28°C during the day and not lower than 12°C at night. When the lowest temperature at night reaches 15°C, start to ventilate all day without covering the film. Apply appropriate amount of urea after planting slow seedlings, and then apply fertilizer every 10 days or so as the tender melons are harvested, applying 10 kg of urea per mu each time. ...

Abstract

The invention provides a highly-efficient multi-cropping technique for greenhouse luffa. The technique is characterized by comprising the following processes: soaking luffa seeds, carrying out germination acceleration, and carrying out seeding; carrying out field planting when the age of a luffa seedling reaches about 40 days and the luffa seedling has four cotyledons with one core; carrying out transplanting in fields and applying the following base fertilizers per mu: 2000 kg of decomposed chicken manure, 50 kg of a ternary compound fertilizer with a content of 25% and 15 kg of urea; carrying out soil preparation, then constructing a ridged field, mulching a plastic film, and finally building a greenhouse frame and covering a film so as to increase temperature; allowing the temperature of a greenhouse to be remained at 25 to 28 DEG C in the daytime and no less than 12 DEG C in the night before the end of March; starting to uncover the film for ventilation all the day when the lowest temperature in the night reaches 15 DEG C; after field planting and rejuvenation, applying a proper amount of urea, and afterwards, applying a fertilizer about every 10 days; since watering is generally not needed before luffa bearing on the basis of sufficient watering for field planting, starting watering after luffa bearing, and allowing the surface of the ridged field to be alternately wet and dry; removing leaves located below 50 cm of the main luffa vine when a luffa vine extends to the top of the greenhouse frame and starts to drop down, then lowering and twining the luffa vine, and rebinding the luffa vine; and generally remaining the main vine to bear luffa, and carrying out artificial supplementary pollination at 7 to 9 o'clock in the morning of the flowering day.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a high-efficiency multiple cropping technology of loofah in greenhouses. Background technique [0002] At present, the loofah cultivation in my country mainly adopts traditional mulching and open-field cultivation methods. The disadvantages are: the concentration of loofahs on the market, resulting in price squeeze competition, short market supply period, and the traditional cultivation mode has low yield and poor income. Contents of the invention [0003] In order to solve the problem of low yield in the traditional loofah cultivation mode, the invention invents a high-efficiency multiplanting technology of loofah in a greenhouse. [0004] In order to solve the above problems, the present invention adopts the technical solution, a kind of high-efficiency multiple cropping technology of loofah in greenhouse, which is special in that it includes the following processes: [000...
