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 treatmen...

Abstract

The invention discloses a method for repairing and planting aquamarine on coastal tidal flats in Jiangsu. The steps of the method are as follows: 1. Selecting a planting area and establishing irrigation facilities; 2. Land preparation after autumn; 3. Pumping and irrigating before freezing in winter; 4. Spring The ice layer melts, draining salt water to preserve fresh water; 5. Sowing of sage greens; 6. Management of sage greens during the growth period; The method of the present invention aims at geographical and climatic characteristics of coastal tidal flats in Jiangsu, fully utilizes local resources, can not only effectively restore saline-alkali land in tidal flats, but also be economical, environmentally friendly, high-efficiency and high-yield. The transformation of saline-alkali land and the sustainable development of agriculture have a positive role in promoting.

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...
