Cultivation method for high-yield of oil sunflower and peanut interplantation on saline-alkali land

Abstract

The invention discloses a cultivation method for high-yield of oil sunflower and peanut interplantation on a saline-alkali land. The method comprises steps of (1) determining a plantation mode for the oil sunflowers and the peanuts as needed, (2) selecting a land, (3) preparing a test field, (4) selecting and processing seeds, (5) sowing and (6) managing the field, wherein in the (2) step, the land has a soil layer having the thickness of 45 to 50cm, soil salt content of a 45 to 50cm root layer is under 0.2 to 0.3%, and the land is flat, has complete irrigating facilities and can be conveniently drained; in the (3) step, rotary tillage during the sowing period is over 25 to 30cm; 2,000 to 3,000 kilograms of excellent farmyard manure and 30 to 40 kilograms of composite fertilizer are applied for each mu before the ploughing; in the (4) step, Peanut breeding No.25 is selected for peanuts and 567DW is selected for the oil sunflower, and the seeds are processed; in the (5) step, spring sowing is conducted from the last ten-day of April to the first ten-day of May and summer sowing is conducted before June,10th; in the (6) step, the field management includes earlier stage management, medium-term management and final-term management. Based on group features oil sunflower and peanut interplanting on the saline-alkaline land, and a combination of great field management measures, output can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of cultivation methods, in particular to a high-yield cultivation method for oil sunflower intercropping in saline-alkali land. Background technique [0002] The development and utilization of saline-alkali land resources in the Yellow River Delta can alleviate the contradiction between population expansion and shortage of cultivated land resources in my country, and can improve soil, increase vegetation, and improve the environment. Planting saline-alkali-tolerant plants, so that a large area of ​​saline soil can be used without engineering improvement, is currently the most environmentally friendly and cost-effective way to improve saline-alkali land. Generally, the salt tolerance and adaptation range of field crops are mostly 0.1% to 0.2%. When the soil salinity exceeds 0.3%, it is difficult for ordinary crops to grow normally, and only a small part of salt-tolerant crops can be planted. [0003] Oil sun...
