Embodiment 1

[0019] The planting method of potato intercropping green manure, with the main purpose of harvesting beans, includes the following steps:

[0020] At the same time that potatoes were planted on the ridges, Longwan No. 2 coniferous peas were planted in the ridges; the planting rate of Longwan No. 2 coniferous peas was 7.5-10 kg per mu, preferably 8.5 kg per mu; wherein, the ridge The width of the ditch is 60 cm, and the width of the ditch is 30 cm; the coniferous peas are planted in two rows in the middle of the ditch, the row spacing is 15 cm, and the plant spacing is 10 cm;

[0021] When the needle-leaf pea seedlings are 5-7 cm high, cultivating and weeding are performed once;

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

[0023] After the coniferous peas are harvested, harvest the stubble 15-20 cm and turn it into green manure, and then water to facilitate the decomposition of the green manure root stubble.

[0024] This example was implemented in the Hexi Oasis Irrigatio...

Embodiment 2

[0027] The planting method of potato intercropping green manure, with the main purpose of mowing and raising livestock, includes the following steps:

[0028] In the early stage of planting potatoes on the ridge, the fast-growing and early-growing Turkmen vetch is planted in the furrow; the sown amount of the Turkmen vetch is 1.5-2.5 kg per mu, preferably 2 kg per mu; wherein the width of the ridge is 60 cm, the The width of the furrow is 30 cm; the Turkmen vetch is planted in two rows in the middle of the furrow, the row spacing is 15 cm, and the plant spacing is 10 cm;

[0029] When the Turkmen hairy vetch seedlings are 5-7 cm high, cultivating and weeding are performed once;

[0030] Turkmen vetch is harvested in the first flowering period;

[0031] After harvesting the Turkmen vetch, harvest the stubble 15-20 cm or turn it all over to make green manure, and then irrigate it to prevent green manure and potato moisture.

[0032] In this example, on the basis of the original potato pl...

Embodiment 3

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

[0036] At the same time when potatoes are planted on the ridges, coniferous peas are planted in the furrows; after the leguminous green manure is harvested, the stubble is harvested or completely pressed for green manure. The sowing rate of coniferous peas is 8.5 kg per acre. The ridge width is 60 cm, and the ditch width is 30 cm. Coniferous peas are interplanted in two rows in the ditch with a row spacing of 15 cm and a plant spacing of 10 cm. When the leguminous green manure seedlings are 5-7 cm high, cultivating and weeding are performed once. Coniferous peas are harvested and leave a stubble 15-20 cm. Coniferous peas are harvested at the pod stage. After the coniferous peas are harvested, the step of irrigation is also included.

Abstract

The invention discloses a planting method of intercropping green manure for potatoes. The method includes the following steps that in earlier stage of planting the potatoes on ridges, leguminous green manure is planted in field ditches, the leguminous green manure is longwan 2 needle leaf pea or Turkmen vicia villosa, and after the leguminous green manure is harvested, stubbles are harvested or totally overturned and pressed to serve as green manure. According to the planting method of intercropping the green manure for the potatoes, the yield is increased and fertilizers are saved without affecting the yield of the potatoes.

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...
