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 Melons are grown in the solar greenhouse of the company, and the variety is Elizabeth muskmelon. 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 110 cm.

[0020] The melons were planted on the protruding belts on both sides of the "concave" shaped cultivation ridge with a plant spacing of 38 cm, and the vines were hung 20 days after planting.

[0021] One set of drip irrigation equipment with its own controller is installed in the solar greenhouse for watering melons, 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 sola...

Embodiment 2

[0027] Example 2 In the same plot, the selected cultivation area is 875m 2 There are three solar greenhouses in the front, middle and rear of the plant to grow melons, and the structures and soil conditions (including soil type and soil fertility, etc.) of the three solar greenhouses are the same. Each solar greenhouse is regarded as one treatment, and the planting variety is Elizabeth.

[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 60 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...

Embodiment 3

[0041] Example 3 In a cultivation area of ​​1200m 2 The melon variety is Huangpi No. 1, which is grown in a 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 70cm 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 watering method for muskmelons in a sunlight greenhouse. The method comprises the following steps: preparing ''concave'' cultivation ridges, wherein each cultivation ridge iscomposed of two convex strips and one concave strip, the width of each convex strip is 20cm, the height of each convex strip is 20cm; and the width of each concave strip is 30cm, the depth of each concave strip is 10cm, and the distance between two adjacent cultivation ridges is 110cm; planting the muskmelons on the convex strips located at two sides of each ''concave'' cultivation ridge; installing irrigation equipment in the sunlight greenhouse for watering the muskmelons, wherein irrigation strips are installed in the middle of each concave strip; and arranging a group of soil moisture sensors on the cultivation ridges to achieve automatically-controlled irrigation. According to the invention, the method can make a soil tillage layer always keeps a proper water content required by growth and development of the muskmelons; after watering and fertilizing are performed, the fertilizer and the water are mainly distributed in the tillage layer, the distribution is uniform, the fertilizer and water utilization rate is high, and the fertilizer usage amount can be reduced; and the water is saved by 15% or more compared with that of a current fertilizer-water integration technology, thenitrogen fertilizer utilization rate is improved by 8.4%, and the fertilizer application is reduced by 12.9% or more.

Description

technical field [0001] The invention relates to a method for watering vegetables in a solar greenhouse, in particular to a method for watering melons in a solar greenhouse that reduces the loss of fertilizer and water. 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.
