Embodiment 1

[0109] 1. Shallow pond lotus root standard construction pond

[0110] 1.1 Site selection for lotus ponds: choose villages with sufficient sunlight and no shade from trees, wasteland at the head of the village, abandoned houses, abandoned pits and ponds, mining subsidence areas, saline-alkali land, and waterlogged depressions.

[0111] 1.2 Standardized pool construction: the cement block pool is dug to a depth of 40cm, and the pool wall is vertical. The bottom of the hammer is used to dig the pool to a depth of 53cm, and the slope of the pool wall is 60°. The built-up depth is 30cm, every 666.67m 2 Use 30cm×20cm cement to cut 770 pieces, 425# cement 12t, sand 60t, Φ0.2mm polyimide film (produced by the reaction of pyromellitic dianhydride and 4.4-diaminodiphenyl ether in a very strong solvent) The resin solution is processed by film forming, high temperature dehydration, etc. The film has excellent heat resistance (200), cold resistance (-60), radiation resistance, water resi...

Embodiment 2

[0150] 1. Shallow pond lotus root standard construction pond

[0151] 1.1 Site selection for lotus ponds: choose villages with sufficient sunlight and no shade from trees, wasteland at the head of the village, abandoned houses, abandoned pits and ponds, mining subsidence areas, saline-alkali land, and waterlogged depressions.

[0152] 1.2 Standardized pool construction: construction of hammer bottom smashing pool. The built pool is 60cm deep, every 666.67m 2 The lotus pond needs 2t of lime, 8t of cement, 30t of sand, and more than 800m of 8 silk film 2 , about 230 prefabricated blocks of 50cm×70cm and 5cm thick; the method is: first, hammer the bottom and smash the side to skim the lime into the bottom of the pool, use a rotary plow to rotate 2 to 3 times, and the depth is 20cm. After the soil and ash are mixed evenly, use a mechanical Level and compact the bottom of the pool, and compact the pool wall with 3:7 lime soil. The second is film laying. After hammering the bott...

Abstract

The invention relates to a method for hydroponic culture by using stalks under net in greenhouse, in particular to a method for hydroponic culture for hydroponic culture by using stalks under net in greenhouse under the condition of facility cultivation. The method comprises the following eight links: sunlight greenhouse construction, shallow pond lotus standardization pond construction, formula balanced fertilization, shallow pond lotus plant, stalk coverage and net fixing, shallow pond lotus management, hydroponic harvest, and storage and sales. The sunlight greenhouse shallow pond lotus cultivation can be appeared on the market in advance or later according to a market situation, so that not only is yield improved, but also the benefit is increased; a shallow pond is constructed for cultivating the shallow pond lotus, so that water and electricity can be saved, and the management and the harvest are favored; by using the method, stalk burning and the CO2 emission can be prevented, the resource advantage is integrated, the reutilization of agricultural wastes is promoted, the environment pollution is reduced, the labor and the effort are saved, the production and the income are increased, the harvest is favored, the yield and the quality of the shallow pond lotus are improved, and the economical and ecological benefits are obvious; and the yield of 666.67 m<2> is more than 4,800kg, so that not only is the yield high, but also the appearance in the market in advance or later is carried out according to the market situation, and the benefit is good.

Description

technical field [0001] The invention belongs to the new technology of aquatic vegetable cultivation in the technical field of facility agriculture cultivation, and in particular relates to a method for water harvesting and cultivation of straw under lotus root nets in shallow ponds in greenhouses. Background technique [0002] Lotus root, referred to as lotus, also known as lotus vegetable, lotus root, etc., originated in my country and has a planting history of more than 3,000 years. It is a very versatile aquatic economic crop. It is not only edible and medicinal, but also one of China's top ten famous flowers. Loved by the masses of the people. The lotus root cultivated for food in my country can be divided into two categories: the first category is the lotus root species. Its rhizome is relatively fat, with white skin, crisp and tender meat, sweet taste, high yield, and few lotus seeds. The second category is lotus species, which mainly harvest lotus seeds. As vegetable...
