Problems solved by technology

[0002] For general water and fertilizer integrated machines, the irrigation time and continuous irrigation time are determined by experience accumulation and experimental data. This method cannot maintain the optimum water content and fertilizer concentration in the soil.
The existing fertilizer-water integration technology has improved the utilization rate of water and fertilizer to a certain extent, but there are still leakage of irrigation water and leaching of nutrients.
At the same time, the opening and closing of drip irrigation equipment in the prior art is controlled by one or a group of soil moisture sensors at the same location, resulting in uneven water distribution around the crop root system when watering

Embodiment 1

[0019] Example 1 In a cultivation area of ​​1200m 2 Zucchini, the variety Weiqing No. 1, was planted in the solar greenhouse. Make a "concave" shaped cultivation ridge consisting of 2 protruding strips and 1 concave strip, with a convex width of 20 cm and a height of 20 cm; a concave width of 30 cm and a depth of 10 cm, and the distance between two adjacent cultivation ridges is 130 cm.

[0020] Zucchini was planted on the protruding belts on both sides of the "concave" shaped cultivation ridge with a plant spacing of 45 cm, and the vines were hung 20 days after planting.

[0021] A drip irrigation equipment with its own controller is installed in the solar greenhouse for watering the zucchini, and the drip irrigation belt is installed in the middle of the sunken belt.

[0022] The soil moisture sensor is installed in the single-point dual-control mode. The specific method is: select a "concave"-shaped cultivation ridge near the middle of the solar greenhouse, and insert a so...

Embodiment 2

[0027] Example 2 In the same plot, the selected cultivation area is 750m 2 Zucchini is grown in three solar greenhouses in the front, middle and back, and the structure and soil conditions (including soil type and soil fertility, etc.) of the three solar greenhouses are the same. Each solar greenhouse was regarded as one treatment, and the planting variety was Weiqing No. 2.

[0028] Treatment 1: The method of the present invention is adopted for the setting of the cultivation ridge and the distribution mode of the soil moisture sensor, and the specific technical scheme is the same as that of Embodiment 1.

[0029] Treatment 2: The cultivation ridges are set in large and small rows, with a large row spacing of 80 cm, a small row spacing of 50 cm, a ridge height of 20 cm, and a ridge width of 20 cm; a drip irrigation device with its own controller is installed in the solar greenhouse, and the drip irrigation belt is installed in the middle of the small rows. Select a small row...

Embodiment 3

[0041] Example 3 In a cultivation area of ​​1050m 2 Zucchini, the variety Weiqing No. 2, was planted in the solar greenhouse. The solar greenhouse is divided into two, one half implements the present invention, and the other implements the existing fertilizer-water integration technology. Verify water and fertilizer savings.

[0042] Treatment 1: The method of the present invention is adopted for the setting of the cultivation ridge and the distribution mode of the soil moisture sensor, and the specific technical scheme is the same as that of Embodiment 1.

[0043] Treatment 2: The setting of the cultivation ridge and the distribution of soil moisture sensors adopt the existing fertilizer-water integration technology. The specific technical plan: the cultivation ridge adopts the existing technology of large and small row settings, with a large row spacing of 80cm and a small row spacing of 50cm. The ridge height is 20cm. The width is 20cm; a drip irrigation device with its o...

Abstract

The invention discloses a method for watering zucchini in a solar greenhouse. Cultivation ridges shaped like a Chinese character 'ao' are made, each cultivation ridge is composed of two convex belts and a concave belt, and the convex belts are 20 cm wide and 20 cm high; the concave belts are 30 cm wide and 10 cm deep, and the interval between two adjacent cultivation ridges is 130 cm; the zucchiniis planted in the convex belts on the two sides of the cultivation ridges shaped like the Chinese character 'ao'; drip irrigation equipment is installed in the solar greenhouse to be used for watering the zucchini, and drip irrigation belts are installed between the concave belts; a group of soil water sensors are arranged on the cultivation ridges, and automatic irrigation control is achieved. The proper water content needed for growth and development of the zucchini is always kept in a soil plough layer, after watering and fertilization are carried out, fertilizer and water are distributedin the plough layer evenly, the utilization rate of the fertilizer and the water is high, and the use amount of the fertilizer can be reduced. Compared with the existing fertilizer and water integrated technology, the water can be saved by 15% or above, the utilization rate of the nitrogen fertilizer is increased by 9.0%, and the application amount of the fertilizer is reduced by 13.7% or above.

Description

technical field [0001] The invention relates to a method for watering vegetables in a solar greenhouse, in particular to a method for watering zucchini in a solar greenhouse to reduce fertilizer and water loss. Background technique [0002] For general water and fertilizer integrated machines, the irrigation time and continuous irrigation time are determined by experience accumulation and experimental data. This method cannot maintain the optimal water content and fertilizer concentration in the soil. The existing fertilizer-water integration technology has improved the utilization rate of water and fertilizer to a certain extent, but there are still phenomena of irrigation water leakage and nutrient leaching. At the same time, the opening and closing of drip irrigation equipment in the prior art is controlled by one or a group of soil moisture sensors at the same location, resulting in uneven water distribution around the crop root system when watering. [0003] How to rea...
