Embodiment 1

[0018] Traditional technology: the ridge distance is 85cm, the ridge width is 55cm, the ridge height is 10cm, and 7kg of potassium fertilizer is applied per mu.

[0019] The water-saving and yield-increasing cultivation method of film-covered peanuts in dry and thin land of the present invention:

[0020] (1) Peanuts are sown on flat ground with a row spacing of 35cm and a hole spacing of 17cm;

[0021] (2) cover soil 3cm after sowing, form the ridge of height 3cm, ridge surface width 55cm, ridge distance 85cm, potash fertilizer bag is applied in the ridge while covering soil ridge, potash fertilizer consumption 8.5kg / mu, increase 21.4% than conventional consumption;

[0022] (3) Laminating in a conventional way;

[0023] (4) On June 28, use 300kg of wheat bran per mu to cover the peanut furrows. Before covering, use 30ml of acetochlor EC per mu (the active ingredient is 100%), add 30kg of water, and spray the furrows.

Embodiment 2

[0037] Traditional technology: the ridge distance is 90cm, the ridge width is 60cm, the ridge height is 10cm, and 7kg of potassium fertilizer is applied per mu.

[0038] The water-saving and yield-increasing cultivation method of film-covered peanuts in dry and thin land of the present invention:

[0039] (1) Peanuts are sown on flat ground with a row spacing of 40cm and a hole spacing of 19cm;

[0040] (2) Cover soil 4cm after sowing, form a ridge with a height of 4cm, the ridge surface is 60cm wide, and the ridge distance is 90cm. While covering the soil and ridges, apply potassium fertilizer in the ridge. The amount of potassium fertilizer is 9.1kg / mu, which is 30% higher than the conventional amount. %;

[0041] (3) Laminating in a conventional way;

[0042] (4) On June 30, use 400kg of wheat straw per mu to cover the peanut furrows. Before covering, use 40ml of acetochlor EC per mu (the active ingredient is 100%), add 30kg of water, and spray the furrows.

[0043] Tabl...

Embodiment 3

[0048] Traditional technology and invention technology cultivation method are the same as embodiment 1. The method described in this invention was used for three consecutive years.

[0049] From Table 5, we can know the effect of this method on soil physical and chemical properties, organic matter content and root activity.

[0050] Table 5 (2006)

[0051]

[0052] It can be seen from Table 5 that, compared with the traditional cultivation mode, the bulk density of the soil in the method of water-saving and yield-increasing cultivation of peanuts covered with plastic film on dry and thin land decreased, and the soil porosity increased by 2.8%-5.0%, and the organic matter content in the 0-15 cm soil layer also increased. The proportion of roots in the middle and lower layers of the soil to the root weight of the entire plow layer increased, and the root activity increased by 11%.

[0053] As can be seen from Table 6, the method of the invention has an impact on the moistur...

Abstract

The invention pertains to agricultural field, in particular to a water saving and production increase cultivation method of plastic-film covering peanut in a poor dry land. The method includes sowing in a flat field, ridges formed by covering soil after sowing, fertilizer application, and covering films. Prior to rainy season, straws of plants are used for covering ridges and furrows which are sprayed by acetochlor herbicide before covering. The method can reduce the rain runoff of soil, reduce the water evaporation volume in the soil cultivation layer, and improve the utilization rate and pod output of peanut, thus realizing the objective of water saving and production increase.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a water-saving and yield-increasing cultivation method for film-covered peanuts in dry and thin land. Background technique [0002] At present, the conventional planting specifications for mulching cultivation in Huanghuaihai peanut production areas are: ridge spacing 85cm-90cm, ridge width 55cm-60cm, ridge height 10cm-12cm, and 2 rows of 3-4cm deep seeding furrows on the ridge For sowing, the row spacing on the ridge is 35cm-40cm, 2 seeds are sown in each hole, and then covered with film. Due to the high peanut ridges of this planting method, the peanuts cultivated in dry and thin land are very susceptible to soil drought stress, which affects the yield of peanuts. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a water-saving and yield-increasing cultivation method for peanuts covered with film on dry th...
