Embodiment 1

[0028] In contrast to the production requirements of water shield green food, the method for planting water shield of water shield in reservoir irrigation canal flood discharge ditch, the following steps are taken:

[0029] A) Water shield field planning: refer to the highest water level of the irrigation canal flood drainage ditch, transform the water level field into a water shield field with a width of about 10 meters, a depth of about 50 cm, and a depth of no more than 1 meter.

[0030] B) Fertilized water shield field: The fertile soil layer at the bottom of the field is 13cm thick, the organic matter content is 2-3%, and the pH value is 4-6. 1,500 kg of decomposed farmyard manure and 75 kg of vegetable cakes are required per mu to prevent chemical fertilizer pollution;

[0031] C) Disinfect and clear the field: remove weeds and Spirogyra, kill snails, sterilize and other harmful organisms. It needs to be disinfected with quicklime, plant ash and other biological pestici...

Embodiment 2

[0036] In contrast to the production requirements of water shield organic agricultural products, the method of planting water shield of water shield in reservoir irrigation canal and flood drainage ditch, the following steps are taken:

[0037] A) Water shield field planning: refer to the highest water level of the irrigation canal flood drainage ditch, transform the water level field into a water shield field with a width of about 10 meters, a depth of about 50 cm, and a depth of no more than 1 meter.

[0038] B) Fertilized water shield field: The fertile soil layer at the bottom of the field is 13cm thick, the organic matter content is 2-3%, and the pH value is 4-6. 1500 kg of high-quality pond mud and 75 kg of vegetable cakes are required per mu. Eliminate chemical fertilizer pollution;

[0039] C) Disinfect and clear the field: remove weeds and Spirogyra, kill molluscs and other harmful organisms. It needs to be disinfected with biological pesticides such as lime and pla...

Abstract

The invention discloses a method for planting water-shield in reservoir irrigation canal drainage ditch water level field. The method includes: A) water-shield field planning: reconstructing a water level field into a waterproof water-shield field with the depth of about 50 cm and having an even bottom, wherein clean water can be injected into and drained out of the water-shield field; B) water-shield fertilizing: applying enough fertilizers before transplanting of the water-shield and germination in spring; C) water-shield field disinfection and cleaning: removing harmful creatures such as weed, snails, fungus and spirogyra; D) transplanting in a suitable season: transplanting the water-shield in any season, but preferably before germination in spring; E) harvesting in suitable time: harvesting the water-shield every 6-11 days while the water-shield substantially covers a water surface; and F) water-shield field management: controlling the water level and the water quality, and eliminating harmful creatures.

Description

technical field [0001] The invention relates to a method for planting water shield, in particular to a method for planting water level field water shield of a reservoir irrigation canal. [0002] technical background [0003] Water shield is a perennial herbaceous aquatic vegetable with shrunken roots. The optimum temperature for growth is 20-30°C. It grows slowly when the water surface temperature reaches 40°C, and gradually stops growing when the temperature is lower than 15°C. In case of frost, the leaves and some stems in the water will die. The remaining stems survive the winter in the water; they like to grow in the shoals with a water depth of about 30-60cm in rivers and lakes, and it is not suitable for growth if it exceeds 100cm; the water level requires relatively stable water flow, and the water environment is rich in oxygen. Since the Song Dynasty, with the increase of the population, the imperial court encouraged the construction of lake fields, the flood storage...
