Embodiment 1

[0023] Salt inhibition efficiency test of straw

[0024] The experiment was carried out in a wheat-corn farmland in 2014. The soil salt content in the plow layer was 2.87 g / kg (measured in October), and the groundwater depth was 1.05m. After the corn is harvested, the straw is crushed, and the amount of soil applied is 350kg / mu (S) and 700kg / mu (2S), respectively, and is mixed with the plow layer soil (0-15cm) through rotary tillage. The treatment without straw is used as a control. Each treatment was repeated three times, with an area of ​​100m 2 . Combined with rotary tillage, 35kg of diammonium was applied per mu. Wheat was sown on October 17th, the variety was Xiaoyan 60, and the next year the wheat turned green and watered once, with urea 15kg / mu. In mid-March, mid-April, mid-May, and mid-June, the plow layer soil (0-20cm) was collected, the salt content was determined by gravimetric method, and the salt suppression efficiency of different straw treatments was calculat...

[0027] Effects of Nitrogen Fertilizer Amount on Growth and Yield of Winter Wheat

[0028] In 2015, an experiment was set up to test the effect of different nitrogen fertilizer application rates on winter wheat production under the condition of straw returning to the field. Three nitrogen level treatments were set up in the experiment: 10 (N1 / 2, calculated as N, the same below), 20 (N1), and 30 kg (N3 / 2) of basal fertilizer per mu of available nitrogen fertilizer, and 7 kg of P fertilizer per mu (calculated as P ), the amount of corn straw returned to the field was 400kg per mu, and the soil salt content was 2.70g / kg. No straw was applied, and 20kg of quick-acting nitrogen fertilizer per mu was used as the control (CK). Each treatment was repeated three times, and the area of ​​the plot was 100m 2 , other management is the same as embodiment 1. When the wheat was harvested, the aboveground biomass and yield of different treatments were measured, and the results are shown in ...

[0031] Effects of Nitrogen Fertilizer Application Patterns on Growth and Yield of Winter Wheat

[0032] In 2015, in winter wheat salinized farmland, three different nitrogen fertilizer application methods were set up: one-time application of 45 kg / mu of available nitrogen fertilizer as base fertilizer (calculated as N, method 1); 15kg / mu (method 2); 30kg / mu of quick-acting nitrogen fertilizer was applied as base fertilizer, 8kg / mu of quick-acting nitrogen fertilizer was applied as green topdressing, and 7kg / mu of quick-acting nitrogen fertilizer was applied during the filling period (mode 3). Each treatment was repeated three times, and the area of ​​the plot was 100m 2 , 7kg of P fertilizer per mu (calculated as P), the amount of corn stalks returned to the field per mu is 400kg, and the salt content of the plow layer soil is 2.65g / kg, and other managements are the same as in Example 1. When the wheat was harvested, the aboveground biomass and yield of different treatments w...

Abstract

The invention belongs to the technical field of agricultural production, and particularly relates to an efficient winter wheat production technology system suitable for being applied in a coastal salinization area. Compared with winter wheat production in a sweet soil area, the system mainly has the innovation points of a technology of restraining salt through straw, a technology of applying nitrogen by stages and the like. Coastal farmland suitable for the technology system is mainly characterized in that the salt content of surface soil is smaller than 3.1 g / kg, and the groundwater depth is larger than 0.85 m. After application and popularization of the system, a significant effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a high-efficiency production technology system of winter wheat suitable for application in coastal salinized areas. Background technique [0002] my country's coastline is long, and salinized soil is widely distributed, accounting for about 4.88% of my country's usable land area. After improvement, it has great potential for increasing production. However, due to the shallow buried groundwater and high salinity in the coastal area, the process of desalination and resalination of salinized soil layers is repeated alternately, making it difficult to control. Affected by this, crops with strong salt tolerance, such as cotton and sorghum, are mostly planted in coastal salinized areas, or are abandoned and left unused. According to estimates, the Bohai Rim region has the potential to increase grain production by 10 billion jin after the implementation of c...
