Embodiment 1

[0024] From 2017 to 2019, a fig planting experiment was carried out on a farm in Caofeidian District, Tangshan City. The specific methods are as follows:

[0025] A method for planting figs in coastal heavy saline-alkali land, comprising the steps of:

[0026] S1. Plot selection: In a farm in Caofeidian District, Tangshan City, the soil in this area belongs to coastal saline soil, and the soil salinity is mainly sodium chloride. The average soil salt content is 11.3g / kg, the pH value is 7.84, and the soil bulk density is 1.68g. / cm 3 , the buried depth of groundwater is 1.4m, and the original soil is the returned beach of aquaculture ponds. This area belongs to the warm temperate zone semi-humid continental monsoon climate, with an average annual rainfall of 635.7mm, concentrated in June to September, accounting for about 81.7% of the annual rainfall, of which July is the most concentrated; build a solar greenhouse, the solar greenhouse greenhouse runs from east to west, the ...

Abstract

The invention relates to a method for planting figs in coastal heavy saline-alkali land. The method comprises the following steps that firstly, a land parcel which is high and dry in terrain and goodin irrigation and drainage and has the total salt content of soil layers of 0-50cm of soil being less than 1.5% is selected to establish a greenhouse, salt drainage pipes are laid in the greenhouse, then soil improvement is performed, then land preparation, bedding, drip irrigation and salt spraying are performed, fresh strong seedlings which are free of diseases and pests and have developed rootsystems are selected for planting, a stem is headed to 20cm-30cm after planting, the seedlings are dripped with water thoroughly, watering is performed according to the soil moisture content in the germination period, the young sprout rapid growth period and the fruit expansion period, drip irrigation is performed once every 7-10 days, watering is reduced before fruit ripening, drip irrigation isperformed once every 15-20 days, and fertilization and topdressing should be noticed. The planting method is easy to operate and low in cost, the planted figs are high in yield and good in quality, and economic benefits of facility cultivation are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of control and utilization of coastal saline-alkali land, and in particular relates to a method for planting figs in coastal heavy saline-alkali land. Background technique [0002] The total area of ​​saline-alkali land in my country exceeds 520 million mu. Coastal saline-alkali land is an important land resource for the development of agricultural production, and it also has the potential to improve the production capacity of agricultural products in our country. There are more than 20 million mu of saline-alkali land along the Bohai coast. The saline-alkali soil along the Bohai coast has heavy clay and poor salt leaching ability. The groundwater has a high salinity, with an average salinity ranging from 11.0g / l to 33.5g / l. The coastal saline-alkali soil area is dry and windy in spring, and the salt return is severe. The climate and soil environment characteristics are not conducive to plant growth. It is ...
