Problems solved by technology

After autumn and winter, the precipitation decreases, the climate is dry, the surface water is short of water, and the soil returns to salt. The coastal area is short of fresh water resources, but rich in salt water resources. However, if the salt water is used directly for irrigation, the soil salt will accumulate, which will have a negative impact on spring agricultural planting.

Embodiment

[0044] Before sowing, the field was pre-treated in the laboratory. The specific method is as follows:

[0045] 1) Prepare the seed soaking solution of Tianjing: excavate the fresh root of Tianjing, grind and crush it, add 50 times the root weight of pure water, put it in an artificial climate box, and soak it at 26°C for 2 days; then take it out and put it in a high-speed centrifuge , set the speed of the centrifuge to 1000r / min and centrifuge at a high speed, take the supernatant after 30 minutes, then place it in a rotary evaporator and evaporate it under reduced pressure to concentrate to 1 / 6 of the original volume, and add 280ml of scallops to each liter of the concentrate The germination agent (the composition of the cyanine germination agent is calculated by concentration: naphthalene acetic acid 30ppm, sodium oxalate 45ppm, calcium chloride 30g / L, H 2 o 2 22.5g / L, sodium nitrophenolate 20ppm) to obtain the soaking solution of Tianjing.

[0046] 2) Germination treatme...

Abstract

The invention discloses a method for repairing and planting sesbania cannabinain in coastal mud flat of Jiangsu province. The method comprises the following steps: 1, selecting a planting area, and establishing an irrigation facility; 2, performing soil preparation after autumn; 3, pumping water for irrigation before freezing in winter; 4, draining salt water to keep fresh water after ice layers thaw in spring; 5, sowing seeds of sesbania cannabinain; 6, carrying out management in a sesbania cannabinain growing period; 7, pressing salt into soil by using rainfall and water storage in a sesbania cannabinain water-storage field; and 8, carrying out harvesting. The method disclosed by the invention aims at the geographic and climate characteristics of the coastal mud flat of Jiangsu province,and local resources are fully utilized, so that saline-alkali soil in the mud flat can be effectively repaired, and the sesbania cannabinain can be produced in an economic, environment-friendly, high-efficiency and high-yield mode. The method provided by the invention is a saline-alkali soil improvement mode with ecological, economic and social benefits, and a positive promotion effect is achieved on improvement of saline-alkali soil in the mud flat and the sustainable development of agriculture.

Description

technical field [0001] The present invention relates to the technical field of continuous agricultural transformation of coastal tidal flats, specifically a kind of Jiangsu coastal tidal flat restoration and planting of echinacea according to the geographical and climate characteristics of Jiangsu coastal tidal flats, making full use of local resources, which can not only effectively repair saline-alkali land of tidal flats, but also be economical, environmentally friendly and efficient method. Background technique [0002] Saline-alkali land is the general term for saline land and alkaline land. It refers to the soil type with a salt content of more than 0.1%-0.2% and an alkalization degree of more than 10%-20%. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkali...
