March entered the fruitful period of strawberry fruition, when the temperature gradually increased, fruit maturation speed, the demand for nutrients is large, so the strawberry seedlings have different degrees of premature aging. In order to improve the economic benefits of farmers, extend the strawberry picking period to the small holiday in May and summarize the following suggestions:
1, increase efforts to spend thinning and fruit thinning
After the small holiday in May, due to the high temperature, the strawberry in the greenhouse will enter the pull-pull period. To extend the picking period and improve the fruit quality, it is necessary to increase the intensity of thinning and thinning fruit at this stage. At present, the flowers on the seedlings and the smaller fruits should all be removed to reduce the consumption of nutrients so that the nutrients can be supplied in a concentrated manner, thereby improving the quality of the reserved fruits.
2, timely soil, seedlings, soil and root
After cultivating, timely cultivating loose soil and increasing soil temperature should be suitable for shallow cultivating when the cultivars are shallow, so as to prevent the soil blocks from pressing down. According to the weather and soil moisture conditions suitable for irrigation, irrigation per acre of water should be poured 4.5KG strawberry special fertilization a barrel to break the consolidation, activation of nutrients, promote root growth and development, enhance water absorption capacity of strawberry roots. At the same time, after falling heavy rain, we must also do a good job of flood control to ensure the normal growth and development of seedlings.
3, timely fertilizer
Due to excessive consumption of strawberry seedlings, coupled with rapid water metabolism at the current stage, it is easy to cause seedlings to die. Therefore, in order to improve seedlings' own nutrient deficiencies, it may be appropriate to supplement nutrient elements and trace elements, spray concentrated phosphorus potassium extract or strawberry. The special foliar fertilizer can, on the one hand, prevent seedlings from dying; on the other hand, it can provide nutrients for the fruit and improve the quality of the fruit.
4, timely adjustment of lighting
During the fruiting period and the vigorous growth period, strawberries need 12-15 hours longer sunshine duration. The most active photosynthetic leaf position is 3-5 leaves. The most effective leaf age is 30-50 days after leaf development. Mature leaves.
The light is sufficient, the plant grows vigorously, the color of the leaves is deep, the flower buds are well developed, and the fruit is sweet and fruity, and can obtain high yield. On the contrary, poor light, weak plants, petiole and inflorescence pedicel, leaf pale, small flowers, and some can not even open, while the fruit color is poor, the fruit is not sweet, poor quality, delayed maturity.
Supplemental lighting at night, insufficient conditions can also be used as a light source incandescent lamp, for additional lighting treatment, each lamp 100 watts lamp about 7.5 square meters area, the lamp frame at 1.8 meters high, from the end of November to mid-February, Every day at 5-10 pm plus 5-6 hours
5, appropriate water control
Do not pour too much water during the strawberry period. Usually you want to see dry and wet. See that the soil is dry and then pour. Pouring too much water is easy to rot the dead seedlings. The fruit is also very sour. The proper control of water can be significant. Increase the sweetness of the strawberries, of course, sweet varieties will be more sweet.
In the result period, water should not be applied as long as it is not dry, which is beneficial to the conversion of strawberry sugar, increasing the concentration of soluble sugar, and improving the sweetness.
6. Early prevention and pest control
In the middle and later stages of strawberry growth, serious pests and diseases are an important factor in causing premature aging. Strengthening pest and disease management can extend the growth period of strawberries and increase yield.
Strawberry diseases include viral disease, verticillium wilt, gray mold, bud blight, powdery mildew, snake eye disease, aphids, thrips, red spider, etc. They should be prevented according to the requirements of plant protection and can be sprayed with thiophanate methyl Amines, azoxystrobin, acetamiprid, ezinozine, thiazolyl and other targeted drugs, improve the utilization of effective pharmaceutical ingredients, consolidate the control effect.
