Seedling culture method for potatoes

Abstract

The invention discloses a seedling culture method for potatoes. The seedling culture method includes the steps of 1, seed potato selection; 2, warm water seed soaking and flushing; 3, seed potato treatment, wherein whole seed potatoes are mixed with bactericide, a nutrient solution and fertilizer, sealing is conducted, and the seed potatoes are subjected to germination accelerating in a greenhouse at the temperature of 15 DEG C to 25 DEG C to be germinated; 4, nutrition pot greenhouse seedling culture, wherein nutrition pots are formed at a time by mixing and extruding of smashed straw, micro element fertilizer and floury soil according to the weight ratio of 1:1:2, degradable net bags are arranged outside the nutrition pots, potato tuber putting holes are reserved in the middle portions of the nutrition pots, germinated seed potatoes are put in the potato tuber putting holes, and the holes are sealed by the floury soil; 5, field transplanting, wherein after growing to 5 cm to 7 cm, the seedlings can be transplanted to a field. According to the seedling culture method for the potatoes, the germination rate of the seed potatoes is increased, development of root systems is promoted, seedling emergence of the potatoes is in order, the seedling emergence rate is high, the seedling culture course is rapid, it is guaranteed that seedlings of the potatoes are cultured in the greenhouse one month ahead of winter and then transplanted to the field, the potatoes can come into the market in advance, the disease-resistant and harmful-bacterium-preventing capacity of the potatoes is improved, and the seedling emergence quality of the seed potato seedlings is guaranteed.

Description

technical field [0001] The invention relates to the technical field of potato planting, in particular to a method for raising potato seedlings. Background technique [0002] Potatoes, also known as ground eggs, potatoes, and yams, are perennial herbaceous plants of the family Solanaceae, and their tubers are edible. They are the fourth most important food crops in the world. Because the tuber contains more nutrients such as starch, rich vitamins and lysine, it is an excellent food with multiple characteristics of grain, vegetables and fruits, and has high nutritional value. my country is a big potato producing country and has rich experience in potato cultivation. At present, the traditional breeding method of potatoes is cutting and sowing, which is easy to lose water, easy to be infected by bacteria, and cause rot; and the seed germination speed and emergence rate directly affect the growth of potatoes in the later stage. The current traditional breeding method has slow s...

Problems solved by technology

At present, the traditional breeding method of potatoes is cutting and sowing, which is easy to lose water, easy to be infected by bacteria, and cause rot; and the seed germination speed and emergence rate directly affect the growth of potatoes in the later stage. The current traditional breeding method has slow seed germination speed and low emergence rate. , the root system is underdeveloped, the breeding process is slow, and the disease and insect pests are serious in the later planting process, resulting in low yield and low quality
