Embodiment 1

[0066] A greenhouse tomato cultivation method based on a small-flow sprinkler, comprising the steps of:

[0067] The drip irrigation belt is buried 30cm below the soil surface, and the main pipe is led out from the water source, usually using Φ63PVC pipe. After the main pipe is led out, connect a water meter first, and then set the sprinkler according to a certain ratio (flow range 50-2500 liters / hour, fertilizer addition ratio 3%-10%) to each plot, and then use the connecting branch pipe, the branch pipe adopts Φ32PE, Connect with capillary by bypass.

[0068] Evenly spread 12-13m per mu before ridge formation 3 Organic fertilizer was used as the base fertilizer; double-row planting was adopted, each row had 4 ridges, the ridge height was 20 cm, the row spacing was 40 cm, and the plant spacing was 33 cm.

[0069] Randomly and evenly take 3 emitters as measurement points, install 2 negative pressure gauges at each measurement point, and monitor the changes in the negative pr...

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 ...
