Method for long-season cultivation of tomato in glass greenhouse

Abstract

The invention discloses a method for long-season cultivation of tomato in a glass greenhouse, which comprises the following steps: (1) greenhouse preparation; (2) cultivation tank preparation; (3) seeding and seedling raising; (4) field planting: sufficient bottom water is supplied, single-row planting is adopted, and nutrient solution is supplied by a proportional fertilizer applicator; and (5) post-planting management: the greenhouse is heated by using an oil furnace, and tomato pests and diseases are well controlled. The tomato cultivation substrate is compounded through fermentation of organic waste, which greatly reduces the cost of the cultivation substrate. Heating is carried out by an oil furnace, and heat is supplied according to the lower limit of temperature, which can reduce the heating cost. Moreover, an internal thermal insulation layer is added, which greatly reduces heat dissipation and realizes the sustainable utilization of daytime solar energy.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for long-season tomato cultivation in a glass greenhouse. Background technique [0002] Tomato, also known as tomato, foreign persimmon, tomato, etc., originated in the Andes region of South America. In Peru, Ecuador, Bolivia and other places, there are still large-scale distribution of wild species. In the 16th century, tomato was introduced to Europe as an ornamental plant, and it was not until the second half of the 18th century that it was used as a vegetable and eaten. The United States began to record edible tomatoes in 1781, but the cultivation was not common, and it was not until the 19th century that it developed rapidly. Tomatoes were introduced into my country around the end of the 16th century or the beginning of the 17th century during the Wanli period of the Ming Dynasty, and they were also used as ornamental plants. By the beginning of th...

Problems solved by technology

The long-season cultivation of tomato is generally raised seedlings in August, planted in September, and ends in July of the next year. During this period, harsh natural conditions such as high temperature in summer and low temperature in winter have been experienced, so there are also the following technical problems: ( 1) The phenomenon of seedlings often exists in summer seedling cultivation, that is, due to the high temperature in summer, the tomato seedlings grow excessively, which is not conducive to the cultivation of strong seedlings; (2) the low temperature in winter is not conducive to the growth of tomato, and it still cannot To meet the requirements of tomato growth, heating is required, thereby increasing the cost of tomato production; (3) At present, most of the tomato cultivation in the long season uses peat, coconut peat, rock wool and other materials, which are expensive and will have adverse effects on the ecological environment. Therefore, the development of a new tomato long-season cultivation substrate is conducive to further reducing tomato production costs and protecting the ecological environment.
