Embodiment

[0032] (1) Deep plowing and balanced fertilization

[0033] For precise sowing of saline-alkali peanut fields, it must be more than 30 cm in winter or spring. Applying acidic organic fertilizers such as chicken manure before deep plowing, and applying 3,000 kg of decomposed chicken manure per mu can effectively reduce the pH value of the soil. Fertilization must be carried out in accordance with the scientific ratio of pure nitrogen, pure phosphorus and pure potassium fertilizers, 15 kg of pure nitrogen, 15 kg of pure phosphorus and 15 kg of pure potassium per mu. Due to the serious lack of calcium in saline-alkali land, 50 kg of superphosphate or calcium magnesium phosphate fertilizer and an appropriate amount of iron fertilizer, zinc fertilizer, molybdenum fertilizer, boron fertilizer and other trace element fertilizers should be added per mu;

[0034] Before sowing, flood with fresh water and press salt. When the local temperature is stable above 15℃, it is the suitable so...

Abstract

The invention relates to the technical field of peanut cultivation, in particular to a saline-alkali soil peanut high-yield cultivation method. The method includes the steps that deep ploughing and balanced fertilizing are conducted; pesticide seed dressing is conducted before seeding; ridging, film mulching and simple grain fine sowing are conducted; chemical control and leaf surface topdressing are conducted; pest control is conducted; optimum-period late harvesting is conducted. According to the saline-alkali soil peanut high-yield cultivation method, the soil environment of saline-alkali soil peanuts is improved, the stress resistance of the peanuts is increased, the rate of emergence is extremely obviously improved, the yield of pods is increased, and the quality of seed kernels is improved. Compared with a conventional saline-alkali soil peanut planting method, the single-plant peanut bearing number is increased by 8.5, the weight of per hundred of peanuts is increased by 35.6 g, the kernel production rate is increased by 5.6 percent, the yield of the pods can reach 403.4 kg / 667 m<2>, the yield is increased by 44.74 percent, the seed kernel protein content is increased by 3.08 percent, the seed kernel fat content is increased by 3.62 percent, the oleic acid content is increased by 14.76 percent, and the specific value of the oleic acid or linoleic acid is increased by 17.09 percent.

Description

technical field [0001] The invention relates to the technical field of peanut cultivation, in particular to a high-yield cultivation method for peanuts in saline-alkali land. Background technique [0002] In recent years, conflicts between peanuts, grain and cotton in Shandong have become prominent. There are about 3 million mu of saline-alkali land in the Yellow Triangle area. If this part of land is used for peanut production, it will greatly increase the self-sufficiency rate of vegetable edible oil in my country. However, in saline-alkali land, due to the high soil salinity, low exchangeable calcium content and low iron element, the yield and quality of peanuts are reduced. Peanut is a calcium-loving crop. Insufficient exchangeable calcium in the soil will seriously affect the development of peanut pods and cause yield reduction. At the same time, as the core substance of the calcium signal transduction pathway, calcium is one of its important roles in regulating the...
