Embodiment 1

[0026] (1) Sowing:

[0027] ① Seed selection and soaking: before sowing, remove miscellaneous, small, insect-eaten, damaged and dull-colored seeds, select and keep the seeds that are uniform in size, plump and of the same color, and spread out the selected seeds to dry for 1 to 2 days. day, 2 to 3 hours a day in the sun. Put the sun-dried seeds into clear water, stir them, and let them stand for 3 hours. First, remove the floating seeds, then remove the plump seeds that sink to the bottom of the water and put them in a container. Add warm water at 45°C to the container to soak the seeds for 15-20 hours. .

[0028] ② Disinfection treatment of seeds: Take out the soaked seeds in ① and put them in a sieve basket to control the water for 30 minutes, then evenly dress the seeds with 50% carbendazim wettable powder, and then dry them in the air.

[0029] ③Preparation of nutrient bowls: Select fertile soil and well-drained fields close to the planting area to build a 2m×15m seedbed...

Embodiment 2

[0040] When conditions permit, magnetically treat the selected seeds before soaking:

[0041] The selected castor seeds are placed in a seed magnetic treatment machine and subjected to magnetic treatment for 10 minutes under a field strength of 2000Gs, so as to improve the germination rate and growth ability of the seeds.

Embodiment 3

[0043] When conditions permit, coating treatment is carried out after seed disinfection treatment:

[0044] Select the seed coating agent made of chitin or derivatives to coat the seeds: the amount of seed coating agent powder is 2% of the weight of the seeds, the amount of water is 1%-1.5% of the weight of the seeds, fully stirred, so that the seed coating agent can Evenly coat the surface of the seeds. Then put the mixed seeds into bags, seal them and store them in the air for 1-2 days before sowing.

Abstract

The invention provides a castor ecological planting method in the seashore saline soil, which achieves the purpose of improving the physicochemical property of soil, increasing the soil nutrient level, improving the castor growth potential and saline-alkali tolerance and reducing the plant diseases and insect pets using the ecological cultivation technologies such as direct seeding ryegrass, magnetism treatment of seed, seed coating, seeding in nutritive cup by phosphate liberation bacteria, wide bean interplanting, improving medium or the like. An effective castor ecological cultivation model in the seashore saline soil is explored, which not only ensures the castor yield and quality, but also improves the saline soil environment, and is useful for pushing the development of the castor industrialization, regulating saline soil agricultural structure, increasing the income of farmers and ecologically restoring the ecosystem of the saline soil. The castor ecological planting method of the invention is of great significance for releasing the national energy shortage, improving ecological environment and facilitating agriculture benefit.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for planting castor on seashore saline soil, belonging to the technical field of ecological agriculture Background technique [0002] With the surge of international oil prices and the resulting energy, economic, and ecological crises, the movement to develop biomass energy instead of fossil fuels has flourished worldwide. Due to its similar properties to petrochemical diesel, safer storage and use, excellent lubricating performance, clean and environmentally friendly, biodiesel is the most promising alternative energy source for fossil fuels. In recent years, castor oil has received more and more attention as a biodiesel blended with traditional diesel for automotive power fuel. In addition, castor oil is also an important chemical raw material for the production of lubricants, plastics, detergents, cosmetics, etc., and its deep-processed products reach more than 3,000 ki...
