Embodiment

[0019] Example: Experiments of Lactobacillus plantarum P-8 and Lactobacillus casei Zhang in potato cultivation.

[0020] Experimental location: Qingdao Jiaoxi Baixingyuan Potato Cooperative (0.8 mu each for Lactobacillus plantarum group, Lactobacillus casei group, compound bacteria group and blank control group)

[0021] Experiment time: 2016.3.17-2016.7.5

[0022] Experimental crop: Potato (variety: Holland 15)

[0023] Dosage and method: start to apply during the potato tuber formation period (from budding to flowering), 2.5 liters / mu (the total number of live bacteria in the bacterial agent used by the experimental group is greater than 10 9 cfu / mL, the number ratio of the two bacteria in the compound bacteria group is 1:1), flood irrigation with water, the irrigation volume is about 20 cubic meters / mu, and the water containing bacteria will not be irrigated in the later stage, but the water without bacteria will be irrigated according to the growth of the crops , to ensu...

Abstract

The invention discloses a compound bacterium agent capable of improving the content of starch and dry substances in potatoes and application of the compound bacterium agent. The compound bacterium agent is composed of lactobacillus plantarum P-8 and lactobacillus casei Zhang. The two bacteria have obvious influences on growth and anabolism of the potatoes; particularly, the content of the starch and the dry substances in the potatoes can be improved, so that relatively ideal raw materials are provided for preparation of potato starch and other high-additional-value products; and meanwhile, the storage period of the potatoes is prolonged.

Description

technical field [0001] The present invention relates to the lactic acid bacteria compound preparation that plant Lactobacillus plantarum (Lactobacillus plantarum) P-8 and casei Lactobacillus (Lactobacillus casei) Zhang and their metabolites form, especially a kind of bacterial preparation that can significantly improve starch and dry matter content in potato, It belongs to the technical field of microorganisms. Background technique [0002] Potato is a perennial herb of Solanaceae, with edible tubers, terminal cymes, white, red or purple flowers; spherical berries, green or purple-brown; kidney-shaped, yellow seeds. The starch content in potatoes is about 9-20%, protein 1.5-2.3%, fat 0.1-1.1%, and crude fiber 0.6-0.8%. Nutrients contained in 100g potato: energy 318 kJ, calcium 5-8mg, phosphorus 15-40mg, iron 0.4mg-0.8mg, potassium 200-340mg, iodine 0.8-1.2, potato element 12-30mg, thiamine 0.03~0.08mg, riboflavin 0.01~0.04mg, nicotinic acid 0.4~1.1mg, tubers also contain g...
