Milk strawberry is a flavor somewhat similar to the milk taste of strawberry varieties, but also in the past two years is a kind of best-selling strawberries, the following is I carefully for you to organize the milk strawberry planting methods, take a look.
Milk strawberry planting method
Selection of land rectification
Strawberry garden should be selected light, terrain a little higher, the ground is flat, irrigation and drainage is convenient, the soil is fertile and loose, the previous crop for beans or onion and garlic vegetables for appropriate, the garden should be in addition to the first weed, the extermination of underground pests. Available 50% phoxim emulsion 1000 times liquid spray (wet soil layer 5-6 cm), control grubs, mole crickets, tigers.
1 week later, mu basal application of high-quality rotted farmyard manure 5000 kg, 100 kg of calcium superphosphate, 50 kg of potassium chloride. Combined with the deep turning of the garden, fine ground preparation, made 20 cm high, 50 cm wide bed, bed ditch width of 30 cm. The length of the trellis is limited to 20 meters, with 4 beds inside.

Replanting technology
In order to strive for the end of January to early February strawberry market, breeding nursery strawberry seedlings transplanted greenhouse beds should be in early September. To start with the seedlings, with transplanting, each bed planted 2 rows, row spacing 27 cm, hole spacing 20 cm, mu planted 12,000 plants. The inflorescences of the plants in the same row were planted in the same direction, so that the strawberry seedlings bowed back toward the inflorescences in the direction of the intended growth, the heart of the seedlings was exposed to the bed, the root system was spread out and buried in the loose soil layer, and the planting water was poured in time, and the exposed roots were buried in the soil layer.
Planting management
1, plowing and fertilization. Plowing loosened the soil, conducive to the decomposition of organic matter. November to December should be shallow plowing 3 times. The first flowering period and the early stage of fruiting each fertilizer 1 time. Mu of urea 10 kg, 20 kg of phosphate fertilizer, potassium chloride 10 kg, or three yuan compound fertilizer 35 kg.
2, the management of the pre-flower bud differentiation. early September transplanted strawberry seedlings, in addition to timely supplemental water, should be covered with shade net shade. The net from the ground 1.2 meters, easy to operate personnel. To timely remove dead leaves, old leaves and axillary buds and stolons, keep 5-6 leaves. Flower bud differentiation needs lower temperature and short sunshine, can be covered with straw thatch (grass curtain) on the shade net. Through the operation process of uncovering and covering straw thatch, artificially create the condition of short sunshine and lower temperature to promote the differentiation of terminal inflorescence and axillary inflorescence for more than a month.
3, irrigation and drainage methods. In the early flowering and berry growth, respectively, irrigation 1 time. It is appropriate to use furrow irrigation, so that the water irrigation to the ditch height of 2/3 is good, so that the water gradually seeped into the bed soil, the remaining water in the ditch discharge.
In case of drought, irrigation should be done once in 5-7 days. With a rubber hose with a section of metal pipe on the front end of the hole irrigation, not only to save water, but also to keep the bed soil loose. When it rains a lot in the fall, drainage should be done in time. Strawberry garden should be done early around the drainage ditch, so that the shed border ditch water can be drained.
4, cover the plastic film. October to early November, is the end of the strawberry inflorescence differentiation period, you can remove the shade net. Jiang quasi-region, ? The winter? After the cover film,? The snow? Before covering the greenhouse membrane, so that the temperature in the shed to maintain 28-30 ℃. Warm winter In the year, the temperature of the greenhouse is maintained at 28-30℃. Winter solstice Cover the middle greenhouse with plastic film at the time of winter solstice. Cold winter Years should be covered with both large and medium-sized plastic film. In short, it is a good idea to cover the large and medium sheds at the same time. The small cold? to? Big Cold? season, the shed temperature should be maintained above 25 ℃, at least 23 ℃ above, only to meet the above temperature, strawberry can grow normally.
5, ventilation operation. Strawberry seedlings growing soil humidity should be 70%-80% is appropriate. The air humidity in the shed is 60% - 70% is good. Therefore, when the air temperature in the shed exceeds 30 ℃, should be ventilated. November to December should be uncovered at 10 a.m. to 3 p.m. in the shed and the middle of the shed at both ends of the plastic film ventilation. When the humidity in the shed exceeds 70%, it should also be ventilated to reduce the humidity of the air in the shed. Flowering shed stocked with bees, can be in the large and medium-sized shed at the two ends of another nylon wire mesh, to facilitate smooth ventilation. Another role of greenhouse ventilation is to prevent strawberry powdery mildew.
6, harvesting. Strawberry seedlings blossom, fruit to berry coloring, softening, release the characteristic flavor, time about 30 days. After the strawberry berries are ripe, they should be harvested and marketed in batches. The average yield of strawberries is 1500 kilograms per mu.
Disease control
1, leaf spot disease: also known as snake eye disease, mainly affecting leaves, petioles, fruit stalks, young stems and seeds. In the leaf blade to form a small dark purple spots, expanded to form a nearly round or oval spot, the edge of the purple-reddish-brown, the center of the grayish-white, slightly fine wheel, so that the whole spot is snake-eyed, the spot does not form a small black grains.
Countermeasures: timely removal of diseased leaves, old leaves. At the beginning of the disease, use 70% chlorothalonil wettable powder 500 times to 700 times liquid, and then spray again after ten days. Or use 70% Dyson Manganese zinc wettable powder, 200 grams per mu to 75 kg of water for spraying.
2, powdery mildew: mainly harms the leaves, but also attacks flowers, fruit, fruit stalks and petioles. Leaf blade upward rolled spoon-shaped. Flower buds and petals are affected with purple-red color, can not bloom or bloom completely, the fruit does not expand, is elongated; young fruit loses luster, hardening. Near-ripe strawberries will lose their commercial value if they are victimized.
Countermeasures: In the center of the disease and its surrounding, focusing on spraying Boomer 0.3 degrees of thiosulfuric acid. After harvesting, cut the leaves of the whole garden, sprayed with 70% metribuzin 1000 times liquid or 50% of the retort 800 times liquid and 30% Teflon 5000 times liquid.
3, gray mold: is the main disease after flowering, in the flowers, petals, fruit, leaves can be onset. In the expansion period of the fruit, the generation of brown spots, and gradually expand, dense gray mold so that fruit softening, corruption, seriously affecting the yield.
Countermeasures: in the bud to the flowering period, with 25% carbendazim wettable powder 300 times liquid, 50% gramicidin wettable powder 800 times liquid, 50% pomocarb 500 times to 700 times liquid spray. Root rot: Starting from the lower leaves, the leaf margins turn reddish brown and gradually wither upward to wither. The pillar in the middle starts to turn black brown and rot, and the center pillar of the root is red. Preventive measures: strawberry transplanting before the use of 40% asparagus green powder 600 times liquid, poured on the bed, and then mulch, leveling transplanting, in order to effectively kill the pathogens in the soil, to reduce the base of the fungus in the field, to reduce the chances of contagion.
4, yellow wilt: the disease is a soil disease, the main symptom is the deformity of the young leaves, leaves turn yellow, leaf surface rough and incomparable. Subsequently, the leaf margins turn brown and wither inward until they die.
Countermeasures: Strictly introduce disease-free plants to plant; shorten the renewal period; use chloropicrin 13.5 liters to 20 liters or solar energy to cover the film irrigation for soil disinfection; those who have developed the disease must be pulled out and burned.
