Greenhouse tomato cultivation method based on small-flow irrigation device

Abstract

The invention discloses a greenhouse tomato cultivation method based on a small-flow irrigation device. The method comprises the following steps of burying of a drip irrigation zone, arrangement of asoil pressure detection system, application of base fertilizer, ridging, field planting of seedlings, application of base fertilizer after field planting, irrigation and topdressing according to a monitoring result and greenhouse management. The irrigation method comprises the step that watering is conducted at nine stages according to the growth period of plants; the topdressing method comprisesthe steps that topdressing is controlled at different stages of the seedling stage, initial flowering stage and fruiting stage, wherein the initial flowering stage is divided into a bud appearance stage and a bud blooming stage, and the fruiting stage is divided into a fruit bearing stage, a fruit expansion stage and a fruit end stage. According to the greenhouse tomato cultivation method, growthof the root systems is stimulated at the tomato seedling stage, biomass accumulation of the root systems is increased, development of the root systems is promoted, the space effectiveness of soil nutrients is changed, the root shoot ratio of crops is increased, the crop yield and water and fertilizer utilization rate are increased, and the fruit quality is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and in particular relates to a greenhouse tomato cultivation method based on a small-flow irrigator. Background technique [0002] The concept of water-saving and efficiency-enhancing is an important force to promote the development of my country's water-saving irrigation technology. my country's water-saving irrigation technology is also constantly emerging, from channel anti-seepage, sprinkler irrigation, micro-sprinkler irrigation, seepage irrigation to drip irrigation, which has been popularized in recent years. The refinement of drip irrigation has been improved to under-film irrigation and underground drip irrigation, the irrigation method has changed, and the concept of water saving and efficiency enhancement has also been greatly strengthened. [0003] Subsurface drip irrigation is a major breakthrough in preventing surface evaporation and increasing water use ...

Problems solved by technology

However, when there is long-term hypoxia, the growth of the aboveground part is severely inhibited, and the leaves will not be able to ensure sufficient carbohydrate delivery to the roots, and eventually the growth of the root system will also be inhibited.
