Problems solved by technology

[0003] However, from July to the first ten days of August, the rainwater is too concentrated and the soil water content is too high, which causes the potato base fertilizer to dissolve too quickly and cause loss, and the high soil water content leads to soil compaction and insufficient oxygen, resulting in poor potato block properties. Regularity and proliferation of lenticels directly affect the commodity properties of potatoes, thereby reducing the output value of potatoes

Embodiment 1

[0032] The planting method of summer-sown potatoes with semi-film mulching specifically includes the following steps:

[0033] Step 1: Planting time

[0034] Choose the 5th day after the Dragon Boat Festival, and sow in fine weather.

[0035] Step 2: Planning the Planting Field

[0036] Sow 3900 ponds per mu, press 115cm off the line, and after pulling the line, open two seeding trenches with a width of 25cm and a depth of 10cm.

[0037] Step 3: Sowing the seeds

[0038] Use 30 kg of general calcium or calcium magnesium phosphate fertilizer, 40 kg of compound fertilizer (17-17-17), and 40 kg of special controlled-release fertilizer for potatoes by mu, evenly apply it into the ditch, and return to 3cm thick fine soil on the fertilizer surface. Then place the seed potatoes (blocks) in the pond or sow them in the ditch according to the pond distance described in step 1, with the buds facing up when placing, and finally apply farmyard manure on the seed potatoes (blocks).

Embodiment 2

[0042] The planting method of summer-sown potatoes with semi-film mulching specifically includes the following steps:

[0043] Step 1: Planting time

[0044] Choose the 7th day before the Dragon Boat Festival, and sow in fine weather.

[0045] Step 2: Planning the Planting Field

[0046] Sow 3,900 ponds per mu, 115cm off the line, and after pulling the line, sow the ponds on both sides of the line, drill the pond with a distance of 33cm, with a large row spacing of 75cm and a small row spacing of 40cm.

[0047] Step 3: Sowing the seeds

[0048] Use 30 kg of ordinary calcium or calcium magnesium phosphate fertilizer, 40 kg of compound fertilizer (17-17-17), and 40 kg of special controlled-release fertilizer for potatoes according to the acre, and evenly apply them into the pond. Place the seed potatoes (blocks) in the pond with the buds facing upwards, and finally apply farmyard manure on the seed potatoes (blocks).

[0049] Step 4: Cover the pond with ridges and cover with...

Abstract

The invention discloses a half-film covering planting method for potatoes sown in summer. Comprising the following steps of reasonable planting time selection, planting field planning, sowing, pond covering and ridging, half-film covering and the like. By means of the planting film mulching method, spring drought can be avoided, soil under the film is not hardened in the month of rainwater gathering, the soil is kept loose, nutrients and sufficient oxygen needed by expansion of potato blocks are provided, potato block deformation and peel hole proliferation are avoided, most of the used fully-biodegradable mulching film is degraded during harvesting, and the yield of the potato blocks is increased. Potato harvesting is not affected, and mulching film pollution is avoided. The problems of poor seedling emergence due to water shortage in spring, soil hardening caused by rainwater concentration in summer, less oxygen in soil and influence on potato yield and commodity characters due to loss of fertilizer along with rainwater are solved, and the method is suitable for popularization and application in the WuMongolian mountain area.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a planting method for summer-sown potatoes with semi-film covering. Background technique [0002] Potato is one of the most important crops in Wumeng Mountains, and it is a pillar industry to consolidate the achievements of poverty alleviation and continue rural revitalization. In recent years, the spring drought in the Wumeng Mountains has become more and more serious. There was almost no rainfall for nearly two months from early April to late May, which had a huge impact on the emergence of potatoes in the spring and caused a serious reduction in potato production. After fully researching and summarizing the climatic characteristics of Wumeng Mountains in the past 10 years, generally the rainy season begins about 10 days after the Dragon Boat Festival, and most of the potato pieces have been dried to death before the Dragon Boat Festival, causing great...
