Embodiment 1

[0019] The planting method of potato intercropping green manure is mainly aimed at harvesting beans, and specifically includes the following steps:

[0020] During the same period when potatoes are planted on the ridge, No. 2 coniferous pea is planted in the furrow; the sowing rate of No. 2 coniferous pea in Longwan is 7.5-10 kg per mu, preferably 8.5 kg per mu; wherein, the ridge 60 centimeters wide, and the furrow is 30 centimeters wide; The coniferous peas are planted in two rows in the middle of the furrow, with a row spacing of 15 centimeters and a plant spacing of 10 centimeters;

[0021] When the height of the coniferous pea shoots is 5-7 cm, intertill and weeding once;

[0022] Coniferous peas are harvested at the pod stage;

[0023] After the coniferous peas are harvested, 15-20 cm of harvested stubble is turned over and pressed as green manure, and then watered to facilitate the decomposition of the green manure root stubble.

[0024] This example is implemented in...

Embodiment 2

[0027] The planting method of potato intercropping green manure is mainly aimed at mowing green and raising livestock, and specifically includes the following steps:

[0028] In the early stage of planting potatoes on the ridge, plant fast-growing and early-onset Turkmen vetch in the ridge; the sowing rate of the Turkmen vetch is 1.5-2.5 kg per mu, preferably 2 kg per mu; wherein, the ridge is 60 centimeters wide, and the The furrow is 30 centimeters wide; the Turkmen vetch is planted in two rows in the middle of the furrow, with a row spacing of 15 centimeters and a plant spacing of 10 centimeters;

[0029] When the seedling height of the Turkmen vetch is 5-7 cm, intertillage and weeding 1 time;

[0030] Turkmen scallops are harvested at the early flowering stage;

[0031] After the Turkmen vetch is harvested, the remaining 15-20 cm or all of the harvest stubble is turned over as green manure, and then watered to prevent green manure and potato moisture.

[0032] In this ex...

Embodiment 3

[0035] The planting method of potato intercropping green manure comprises the following steps:

[0036] At the same time as potatoes are planted on the ridge, peas are planted in the furrow; after the leguminous green manure is harvested, stubble is harvested or all turned over to be used as green manure. The sowing rate of coniferous peas is 8.5 kg per acre. The ridge width is set to 60 cm, and the furrow width is 30 cm; two rows of coniferous peas are interplanted in the furrow, with a row spacing of 15 cm and a plant spacing of 10 cm. When the height of the leguminous green manure seedlings is 5-7 cm, intertill and weeding 1 time. Coniferous peas are harvested with a stubble of 15-20 cm. Coniferous peas are harvested at the pod stage. The step of watering immediately after the coniferous peas are harvested is also included.

Abstract

The invention discloses a potato intercropping green manure planting method, which comprises the following steps: in the early stage of planting potatoes on a ridge, plant a leguminous green manure in a furrow, and the leguminous green manure is Longwan No. 2 coniferous pea or Turkmen vetch; After the leguminous green manure is harvested, the stubble is harvested or all turned over to be used as green manure. The potato intercropping green manure planting method proposed by the invention can increase income and save fertilizer without affecting potato yield.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for planting potato intercropping green manure. Background technique [0002] Potatoes, also known as potatoes, are also called artichokes. For one season or two seasons a year cultivation. Underground tubers are round, egg, oval, etc., with bud eyes, red, yellow, white or purple skin. Aboveground stems are prismatic and hairy. Odd-pinnate compound leaves. Cymes terminal, flowers white, red or purple. Berry spherical, green or purple-brown. Seeds reniform, yellow. Multi-purpose tuber propagation. Can be used as medicine. According to the analysis of nutrition expert Li Shuyun, the potato vitality index is 8.6, which proves that it is effective in improving vitality; the disease prevention index is 126.67, which belongs to the high index range. [0003] It is more suitable for planting in irrigation areas and semi-arid and semi-humid arid areas with an altitude of l...
