A Greenhouse Tomato Cultivation Method Based on Small Flow Emitter

Abstract

The invention discloses a greenhouse tomato cultivation method based on a small-flow sprinkler. The method comprises the steps of: burying drip irrigation belts, setting a soil pressure detection system, applying basal fertilizer, and ridging, then planting seedlings, and applying base fertilizer after planting; according to the monitoring results, watering and topdressing; at the same time, shed management; said The method of watering is: according to the growth cycle of plant, be divided into 9 phases and carry out watering; The method of described topdressing is: control topdressing according to the different periods of seedling stage, early flowering stage and every ear fruit stage; Wherein the early flowering stage is divided into flower bud emergence stage and The flower buds have been opened; the fruiting period of each ear is divided into the fruit setting period, the expanding fruit period and the final fruiting period. The cultivation method of the present invention stimulates the growth of the root system at the tomato seedling stage, increases the biomass accumulation of the root system, promotes the development of the root system, changes the spatial availability of soil nutrients, and increases the root-to-shoot ratio of crops, thereby improving crop yield, water and fertilizer utilization rate and fruit quality. .

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 ...

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.
