Management techniques of flowering and fruiting period of Potato

Cultivate soil, when the phenomenon of thin ridge narrow soil, easy to produce green potato, must be combined with cultivated soil 1 time, thick 2~3 cm, cover the whole plastic film, to prevent this phenomenon.

Foliar fertilizer spraying: urea + photosynthetic nutrient film fertilizer should be sprayed on the leaves of potato plants with weak growth and yellow leaves in time to help plants absorb a large amount of light fertilizer, light energy, light, compatible conventional fertilizer and nutrients to supply plants to grow and develop to the limit.

Control excessive growth, plant growth is particularly vigorous. It is necessary to spray Huawang No.3 in time to regulate and promote the transformation from vegetative growth to reproductive growth.

Water management: water should be irrigated once after seedling stage, water demand should be ensured in bud stage, flowering stage and tuber setting stage, water should be irrigated once according to weather conditions in these three stages, so as to increase soil moisture and cool down.

Pest control, disease damage, found that the center of the disease plant timely spray tree general disinfection sterilization, and timely control with targeted chemicals. Pests damage potatoes. At the beginning of larval use of targeted agents, every 6 to 8 days spray 1, continuous spray 2 to 3 times.
