Embodiment 1

[0020] Example 1: High-multiplication method of two-cropping peanuts in one year

[0021] （1） Regional selection: Choose the northern region where the temperature reaches above 15°C in late March and stabilizes at around 25°C in mid-October.

[0022] （2） Sowing in the first season: Spring land should be reserved for planting in the first season. Plow 25-30cm deep before winter, so that the field has good permeability and suitable tightness. Before sowing in the following year, shallow plow 10-12cm, apply 22.8Kg of urea, 44Kg of superphosphate, 14.5Kg of potassium chloride, 0.75Kg of boric acid, and 45Kg of calcium sulfate per mu.

[0023] In mid-March, when the local temperature reaches above 12°C, ridges are sprayed with herbicides and then covered with plastic film; in late March (covered with plastic film for one week or when the temperature reaches 15°C), water in an appropriate amount along the ditch according to the soil moisture, and the watering amount is about I...

[0031] Example 2: High-multiplication method of two-cropping peanuts in one year

[0032] The experiment was carried out in Yuanyang Experimental Base of Henan Academy of Agricultural Sciences in 2013. Before winter, select fields with good permeability and suitable tightness, plow 25-30cm deep, and shallow plow 10-12cm before planting in the following year, and apply 22.8Kg of urea per mu, Superphosphate 44Kg, Potassium Chloride 14.5Kg, Boric Acid 0.75Kg, Calcium Sulfate 45Kg, level and rake firmly, and pour water on the soles of the feet.

[0033] On March 12, 2013, the ridges were sprayed with herbicides and then covered with plastic film. On March 22, holes were drilled on the plastic film for sowing. 2 rows, row spacing 30-35cm on the ridge, ridge width 60-65cm, hole spacing 13-15cm, 2 seeds per hole; build a plastic shed on the sowing area, the shed is 30-50cm high and 90-100cm wide, every 1-1.5m to erect arch shed poles.

[0034] When the temperature in the shed rea...

[0037] Example 3: High-multiplication method of two-cropping peanuts in one year

[0038] The experiment was carried out in Yuanyang Experimental Base of Henan Academy of Agricultural Sciences in 2013. Before winter, select fields with good permeability and suitable tightness, plow 25-30cm deep, and shallow plow 10-12cm before planting in the following year, and apply 22.8Kg of urea per mu, Superphosphate 44Kg, Potassium Chloride 14.5Kg, Boric Acid 0.75Kg, Calcium Sulfate 45Kg, level and rake firmly, and pour water on the soles of the feet. On March 12, spray herbicides on the ridges and cover them with film. Select medium and early-maturing peanut varieties such as Yuhua 9936, and drill holes on the film on March 22. The diameter of the holes is 5 cm, the sowing depth is 4 cm, and 2 rows per ridge , the row spacing on the ridge is 35cm, the width of the ridge is 65cm, the hole distance is 15cm, 2 seeds per hole, and a plastic shed is built on the sowing area. The shed is 30...

Abstract

The invention relates to a double-cropping-a-year peanut high-multiple cultivation method. The method comprises the following steps that a field parcel is selected and deeply ploughed before winter, shallow ploughing is conducted before seed sowing next year, ridging is performed on the middle ten days of March, and the field parcel is covered with a mulching film after a weed killer is sprayed; seed sowing for first cropping is conducted when the temperature reaches over 15 DEG C one week after the field parcel is covered with the mulching film, holes are punched in the mulching film for seed sowing, and plastic arched sheds are built above seed sowing areas; all the arched sheds are removed when the outside air temperature stably ranges from 23 DEG C to 26 DEG C in mid-to-end May, and the first cropping is conducted on the last ten days of June; fresh seeds after the cropping are soaked with ethephon for 24 hours, seed sowing for second cropping is conducted, land leveling after the peanut cropping is conducted, ridging, mulching film coverage and seed sowing are conducted, and the second cropping is conducted in mid-to-end October. According to the double-cropping-a-year peanut high-multiple cultivation method, the double-cropping propagation coefficient can reach 150-210 times, the seed breeding process can be accelerated, seed breeding efficiency is improved, and seed breeding cost is lowered. The double-cropping-a-year peanut high-multiple cultivation method has the advantages of being easy and convenient to implement, low in cost, good in effect, high in success rate and the like, and provides a novel technique for large-area low-cost high-quality peanut seed breeding in the northern China.

Description

technical field [0001] The invention relates to a method for planting peanuts, in particular to a high-multiplication method for realizing two crops a year by artificially adjusting the maturity period of peanuts. Background technique [0002] Peanut is the main oil crop and an important economic crop in my country. The peanut planting area in the northern peanut area accounts for about 60% of the total area of ​​the country. The cultivation systems mainly include spring peanuts, wheat ridge interplanting and summer direct seeding peanuts, all of which are cultivated once a year. Way. The low reproductive coefficient of peanuts, the large amount of seeds used, and the slow promotion speed are the main restrictive factors for the transformation of peanut breeding and new varieties into actual productivity. In order to solve the technical problems of long peanut breeding cycle and low breeding coefficient of improved varieties, some breeding units have carried out peanut multi...
