Cultivation method of green food potato

Abstract

The invention discloses a cultivation method of a green food potato. The method comprises the following steps of selecting soil which is loose in soil texture, high in air permeability, deep in soil layer, great in drainage and irrigation condition, flat in terrain and rich in organic matter and applying 2,000-2,500 kg / mu organic fertilizer to land, wherein in the first year, deep tillage is carried out, the depth of deep tillage is 25-35 cm, and correspondingly the land is exposed to the severe coldness of winter and the sunlight; in the next year, conducting deep ploughing and raking and forming high-yield ditches, wherein the width of the ditches is 15-20 cm, the depth is 15 cm, the width of furrows is 160 cm, and excavated soil is uniformly thrown in the middle of each furrow, so thatthe surfaces of the furrows are slightly arched. According to the method, the problems that potatoes are threatened by too many diseases and pests and are poor in quality are solved. The yield of thepotatoes is increased, the economic benefit is high, the use amount of chemical fertilizer is reduced, the soil can be effectively prevented from being deteriorated, and the ecological environment isprevented from being damaged; by adopting the high-yield ditches for planting, the growth of potato tubers is promoted, a potato fruiting layer is thickened, the potato tubers are prevented from beingexposed, the yield is increased, and the quality is improved.

Description

technical field [0001] The invention relates to the technical field of potato cultivation, in particular to a method for cultivating green food potatoes. Background technique [0002] Potatoes are perennial herbaceous plants of the family Solanaceae, and their tubers are edible. They are the fourth most important food crops in the world, second only to wheat, rice and corn. Potatoes are also called ground eggs, potatoes, and potatos. , and wheat, rice, corn, sorghum and become the world's five major crops, potato protein nutritional value is high, potato tubers contain about 2% protein, protein content in dried potatoes is 8% to 9%, according to research, the protein nutritional value of potatoes It is very high, its quality is equivalent to egg protein, easy to digest and absorb, and better than other crop proteins, and potato protein contains 18 kinds of amino acids, including various essential amino acids that cannot be synthesized by the human body. The nutritional value...

[0002] Potatoes are perennial herbaceous plants of the family Solanaceae, and their tubers are edible. They are the fourth most important food crops in the world, second only to wheat, rice and corn. Potatoes are also called ground eggs, potatoes, and potatos. , and wheat, rice, corn, sorghum and become the world's five major crops, potato protein nutritional value is high, potato tubers contain about 2% protein, protein content in dried potatoes is 8% to 9%, according to research, the protein nutritional value of potatoes It is very high, its quality is equivalent to egg protein, easy to digest and absorb, and better than other crop proteins, and potato protein contains 18 kinds of amino acids, including various essential amino acids that cannot be synthesized by the human body. The nutritional value of potatoes is highly evaluated. It is distinguished from the presence of lysine, tryptophan, histidine, arginine, phenylalanine, valine, leucine, isoleucine and methionine in its tubers which contain high grade protein and essential amino acids. If not, the potatoes planted by the existing planting methods have problems such as many diseases and insect pests and poor quality, which make it difficult to achieve new breakthroughs in potato production. In addition, due to the large investment in seed potatoes, chemical fertilizers, and pesticides, not only the economic benefits are low, but also Deteriorating the soil and destroying the ecological environment
