Rice straw plays a very important role in fertilizing the soil and improving the fertility of cultivated land. However, the traditional method of turning rice straw into the field is time-consuming, labor-intensive, and has low economic added value, so it is difficult to be accepted by farmers.
As a result, a large number of rice straws are burned or discarded in the countryside, which not only wastes resources but also pollutes the environment

Embodiment 1
[0043] In 2011, in Ankang Township, Anxiang County, 15 mu of arable land was selected for reorganization. On November 18, 2011, deep dry plowing (plow layer greater than 25cm) was carried out to level the land, and ditches were dug according to the potato planting technology. Ditch the furrow surface with a width of 30 cm and a depth of 15 cm. The potato variety is "Zhongshu No. 3". The specific farming operations are as follows:
[0044] 1. On November 21, select seed potatoes with a size of about 30-50 g that do not contain major viruses and viroids, ring rot, late blight, and root-knot nematode, and have no obvious symptoms of dry rot, soft rot, and silver rough skin. When sowing, place the seed potatoes directly on the furrow surface with the bud eyes facing upwards, arrange the potatoes according to the row spacing of 50cm and the plant spacing of 20cm, and sow about 5,500 plants per mu. The amount of fertilizer per mu is 15kg of urea, 60kg of calcium magnesium phosphat...
Embodiment 2
[0050] In 2011, 18 mu of arable land was newly reorganized in Chaxi Town, Xinhua County. On November 20, 2011, deep dry tillage (plow layer greater than 25cm) was carried out, the land was leveled, furrows were dug according to the potato planting technology, and furrows were dug according to the width of 1.5m. The width of the furrow was 25cm and the depth of the furrow was 20cm. The potato variety is "Feverita". The specific farming operations are as follows:
[0051] 1. On November 19th, dry the seeds. Put the seed potatoes under the condition of 10-15°C with scattered light for 10-15 days, and put them in the sun for 3 days.
[0052] 2. On October 22, choose seed potatoes with a size of about 30-50g. When sowing, place the seed potatoes directly on the furrow surface with the bud eyes facing upwards, arrange the potatoes according to the row spacing of 50cm and the plant spacing of 20cm, and sow about 5,500 plants per mu. The amount of fertilizer per mu is 15kg, 60kg of...

Abstract
The invention discloses a potato fertility improving method for carrying out straw field changing and returning on newly-prepared farmland. The potato fertility improving method includes the steps of selecting the newly-prepared farmland to carry out straw field changing and returning to plant potatoes, rapidly improving the fertility of soil of the newly-prepared farmland through straw and potato straw, deeply plowing the newly-prepared farmland in the mid-to-late September to enable the thickness of the plowed layer to be larger than 25 cm, ditching furrows according to the potato planting technology, leveling the farmland, applying base fertilizers which include, by mass, 10 kg-15 kg per mu of urea, 30 kg-50 kg per mu of calcium magnesium phosphate fertilizers and 40 kg-50 kg per mu of potassium sulfate at a time, planting the potatoes with the standard of 5000 holes-6000 holes per mu, covering ridges with prepared straw with the standard of 400 kg-600 kg per mu, conventionally managing the planted potatoes, harvesting the potatoes in the mid-to-late April next year, and carrying out cyclic operation of farming work such as preparing next-stubble crop planting and the like. The potato fertility improving method is high in economic benefit, after the potatoes are harvested, the potato straw and the decayed straw serve as organic materials to be directly returned to the farmland, and the good effects on the rapid fertility improvement and the physical and chemical property improvement of the soil of the newly-prepared farmland are achieved.
Description
technical field [0001] The invention relates to a method for fertilizing potatoes by returning straw to the field on newly arranged cultivated land. Background technique [0002] Potatoes are loved by people because of their high nutritional value and resistance to storage and transportation. However, the traditional extensive cultivation methods and unscientific management will result in low yield and poor commerciality of potatoes. Therefore, improving the level of potato cultivation technology is still one of the main measures to improve potato yield and economic benefits. However, in land consolidation and standard farmland construction, most areas only pay attention to the increase of cultivated land area, and do not pay enough attention to the quality of cultivated land. The newly added cultivated land is generally poor in fertility, the soil nutrient content decreases, the cultivated layer becomes shallower, and the land is coarse and bony. The degree of maturity is...
