Scientific selection and transplanting choose high-yield, disease-resistant, high-quality varieties. Select 5 seedlings with more than leaves, try to choose the rainy day or sunny afternoon after 4 pm with soil to transplant, so that “not buried in the roots, do not leak rootsâ€, the new stems of the bow are all outward, after planting Drench the water and keep the soil moist. The depth of colonization is appropriate to the level of the base of the seedling and the surface of the soil.
Nutrient fertilization, strawberry nutrient ratio is 1:0.25:1 for nitrogen, phosphorus and potassium, 5,000 kg of organic fertilizer per acre, 30 kg of diammonium phosphate, 30 kg of potassium sulfate, and appropriate amount of active biological bacteria, after application Deep plowing 25 centimeters, fine smashing 2 times, pouring enough water at the bottom, combined with rotary ploughing into the soil. Each year, frozen water is poured on the winter season and covered with ice. In production management, the old leaves, weak shoots and stolons are removed in batches, and thinning and fruit thinning are performed in time.
The main pest control, blight, root rot: all soil-borne diseases, with beneficial bacteria into the 500 to 800 times the entire process of mixing soil or rooting with water. Improve the micro-environment of the soil and use the fertilizer to mix the manure with fertilizers. Early detection of the diseased plants in a timely manner 700 times with a good friend plus Scherfing 300 times the root water, or with Yiwei 800 times the root water, the diseased plants around the more poured, other healthy strains of normal pouring.
Botrytis cinerea: Controlled between budding and flowering, use 25% carbendazim WP 300 times, 50% Kedan WP 800 times, or 50% acetaminophen 500~700 times etc. spray.
Powdery mildew: mainly pay attention to high humidity and no convective wind weather. Bami 0.3-degree lime sulfur was sprayed on and around the affected center strain. Before the inflorescence is revealed until flowering, spray protector Paula or Dasheng M-45 and so on. In the early stage of disease, spray 75% chlorothalonil WP 500 times, or 40% carbendazim 800 times, spray once every 7-10 days, and spray 3 times continuously.
Brown spot disease: It is prone to occur when the content of soil organic matter is low, humidity is high, and light is insufficient. The film was swabbed, and the temperature was raised. The temperature of the leaves was sprayed with a 1000-fold solution of the prochloraz compound plus a photosynthetic accelerator 500 times and a molar protein fertilizer 600 times.
Insect pests: biological control based on pest species. Methods: Azadirachtin 1000 times spray (without affecting bee pollination) 2 to 3 times to achieve control effect, but also promote fruit enlargement. Aphids can be sprayed with 1000 times of imidacloprid, red spider with 800 times of matrine spray all over the field, or 5% of acele 500 times plus azadirachtin 1500 times spray.
