Efficient cultivation method of tomatoes

Abstract

The invention discloses an efficient cultivation method of tomatoes. The efficient cultivation method specifically comprises the following steps of preparing nutrient solution by using fertilizers, which are required in every growth cycle of the tomatoes; absorbing the nutrient solution to form solid nutrient solution by a water-absorbent resin according to a function of repeatedly absorbing hundreds of times of water of the high water-absorbent resin; forming a cultivation ridge according to a conventional method and opening a fertilization groove, then applying the solid nutrient solution and planting tomato seedlings; when dressing the fertilizer at the later stage, diluting the fertilizer to the liquid nutrient solution and pouring; carrying out pest control and management according to a conventional method. Through applying the efficient cultivation method, the high water-absorbent resin at the cultivation ridge can repeatedly absorb and store the rich water, and the rich water is slowly released to be absorbed by the tomato seedlings during drought. The efficient cultivation method completely meets the reasonable requirements that the tomatoes need much moisture, but the tomatoes are not frequently and extensively irrigated, the water fertilizer is fixed by the high water-absorbent resin and is slowly released, the water fertilizer can be completely absorbed by the tomatoes in a balanced manner for a long time, and the water fertilizer cannot be lost and wasted.

Description

technical field [0001] The invention belongs to the field of new plant cultivation techniques, and in particular relates to a high-efficiency cultivation method for tomatoes. Background technique [0002] Tomato, also known as tomato, is rich in nutrients and has a special flavor. [0003] Tomato is a temperature-loving vegetable. Under normal conditions, the optimum temperature for assimilation is 20-25°C, and the optimum soil temperature for root growth is 20-22°C. Raising the soil temperature can not only promote root development, but also significantly increase the content of nitrate nitrogen in the soil, accelerate the growth and development, and increase the yield. Tomato is a light-loving crop, the light saturation point is 700001x, and the suitable light intensity is 30000-500001x. Tomatoes are short-day plants. Short-day sunshine is basically required during the transition from vegetative growth to reproductive growth, but the requirements are not strict. Some var...

Problems solved by technology

[0006] In the traditional cultivation method, in the water and fertilizer management process, the water and fertilizer applied are easy to lose, which not only causes waste, but also affects the yield of tomatoes due to insufficient water and fertilizer.
