Embodiment 1

[0017] Embodiment 1, the salt water irrigation of tomato

[0018] The commercial name of the tested tomato variety is "Zhongza No. 9". It is divided into spring planting and summer planting. The spring planting was sown on February 1, 2007, and it was planted in a large flower pot with a diameter of 20 cm and a height of 20 cm on March 16, 2007. , grown in a greenhouse. The summer colonization was planted on April 1, 2007, and was colonized on May 10, 2007 to a diameter of 20 cm, a large flowerpot of 20 cm high, and grew in a greenhouse.

[0019] The daytime temperature of the greenhouse is 22-30°C in spring, 15-20°C at night, the relative humidity is 60%-80%, and the light is 16 hours a day. The temperature of the greenhouse in summer is higher than that in spring, 25-33°C during the day and 18-23°C at night, and the other conditions are the same. The substrate is peat soil with basal fertilizer: vermiculite = 1:1, and the field water holding capacity of the substrate is ab...

Abstract

The invention discloses a method for irrigating tomatoes with saline water. In the method, saline water irrigation is carried out on tomatoes in any one of flowering and fruit setting period, a first cluster fruit expanding period, a second cluster fruit expanding period or harvesting time, and the tomatoes are irrigated with fresh water in other periods; wherein, the flowering and fruit setting period is from a first flower blossom to diameter of a first cluster fruits being up to 2cm; the first cluster fruit expanding period is from the diameter of the first cluster fruits being up to 2cm tothe diameter of a second cluster fruits being up to 2cm; the second cluster fruit expanding period is from the diameter of the second cluster fruits being up to 2cm to the first fruit harvest; the harvesting time is from the first fruit harvest to harvest completion; and mineralization degree of the saline water is 2g / L-10g / L. The water-saving irrigation method is of practical significance for water-saving agricultural production.

Description

technical field [0001] The invention relates to a method for irrigating tomatoes with salt water. Background technique [0002] China's annual average total water resources are about 28124×10 8 m 3 , of which the total river runoff is 27115×10 8 m 3 , groundwater resources 8288×10 8 m 3 , the total amount ranks sixth in the world, while the per capita share is only 2314m 3 , which is only 1 / 4 of the world level, ranking 88th. The geographical distribution of water resources is also extremely uneven. More than 80% of the water resources are concentrated in the Yangtze River Basin and the areas to the south, accounting for 42% of the country's population and 62% of the arable land in the northern arid and semi-arid areas. The total water resources only account for 20%. The area is severely water-scarce. Water shortage is also a problem that countries all over the world are facing. As the demand for water exceeds the growth of water supply, it has become a trend to cha...
