Abstract
The invention provides a seed dressing and germination accelerating method for seed potatoes, comprising the steps of taking ungerminated seed potatoes, soaking the seed potatoes in seed soaking solution for 20min, and taking out and draining the seed potatoes; putting the seed potatoes on a germination bed, and alternatively placing the seed potatoes and a germination medium in a layered mode, wherein there are 3-4 layers of seed potatoes; and germinating the seed potatoes for 13 days at 18 DEG C and under wet condition. The method of the invention changes traditional potato planting into potato putting and potato digging into potato picking, and potatoes are not damaged, take on a fresh color and have good commercial characteristic. There is little need for inter-tillage or soil loosening after planting, and weeds can be removed manually. By adopting the cultivation method, the sprouting ratio is high, seedlings emerge in order, pests and diseases are easy to control, and water and fertilizer are saved.
Description
Technical field
The present invention relates to potato culture technical field, particularly relate to a kind of rice straw for potato no-tillage with straw mulch cultivation method and seed potato is dressed seed, the method for vernalization process.
Background technology
Potato is also known as potato, potato, potato, potato etc.Potato tubers contains the protein of about 2%, and during potato is dry, protein content is 8% ~ 9%.The protein nutritive value of potato is very high, and its quality is equivalent to the protein of egg, and easily digestion, absorption, be better than the protein of other crops.And the protein of potato contains 18 seed amino acids, comprise the various essential amino acids that human body can not synthesize.The nutritive value of high evaluation potato is that the existence containing the lysine of high-grade protein and essential amino acid, tryptophan, histidine, arginine, phenyl alanine, valine, leucine, isoleucine and methionine with its stem tuber is undivided.
Potato raw long period is short, strong adaptability, per unit area yield are high, stem tuber is nutritious, of many uses, be the fourth-largest cereal crops being only second to paddy and wheat, corn in the world.The traditional cultivation method of potato broadcasts front soil deeptillage, smooth again, applies base fertilizer simultaneously; Then ditched furrow, dig bunch planting kind potato, then earthing lid kind, growth and knot potato environment in order to improve potato in process of growth also will carry out 2 ~ 3 cultivation and bankings; Also soil to be opened when gathering, digging potato one by one.The shortcoming of this cultivation method is that potato ties potato in soil, the extruding of earth is subject to when stem tuber expands, be unfavorable for expanding of stem tuber, the resistance suffered when non-sandy loam is larger, general knot potato is smaller, and big-and-middle potato rate is low, and this implantation methods trivial operations, labour intensity is large, effort of taking a lot of work.The no-tillage cultivation method of potato potato, is the new cultivation method of potato, can greatly overcomes above-mentioned deficiency.
Summary of the invention
The object of the present invention is to provide a kind of rice straw for potato no-tillage with straw mulch cultivation method and seed potato is dressed seed, the method for vernalization process, to solve the problems of the technologies described above.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of rice straw for potato no-tillage with straw mulch cultivation method, is characterized in that, comprise the steps:
