There are three things critical to the strawberries: warm humidity control, water fertilisation, early disease prevention, cyclicality, colourful fruit and high prices。
Site selection and soil preparation
- land parcels: anti-backwind, easy to drain and drain, ph 5. 5-6. 5 micro-acid border land with no connection。
- stationing: east-west, with 0. 06 – 0. 08 mm drip-free membrane, with two layers of membrane/grass protection; excavating cold ditches。
- whole floor: 30 cm deep, 5-7 days sun, 25-30 cm high, 40-50 cm wide and 30 cm wide, which is conducive to the wetting of the decomposition fruit。
- soil sterilisation: 20-30 days of tan in the summer membranes, or treatment with cotton-mounted granules, eradication of roots, anthrax, etc。
Ii. Varieties and planting (applies to the north)
- varieties: contributed to the planting of red-coloured, zhang ji and yano; the open selection of sweet charlie, frankland; and the selection of monterey in the yangtze basin。
- standards for seedlings: one centrifugal, coarse and disease-free。
- time: late august — mid-september, not later than early october; election day or evening planting。
- density: two-line triangles, 15-20 cm, 25-30 cm and 8,000 per 10,000 cm。
- planting points: deep, shallow and bow-backed into the gutter; plantings are followed by steady water, which is light in three days。
Temperature and light management
- temperatures: 25-28°c in the daytime, 8-12°c in the night, 22-25°c in the daytime, 8-10°c in the night of the flowering period, 20-25°c in the daytime, 5-8°c in the night in the daytime of the inflation period, and temperature increase below 5°c。
- humidity: the air is 50 per cent-60 per cent relatively wet; dripping with membranes, morning ventilation is wet, and night-to-night leaves are exposed。
- light: direct light for six hours per day; light for rain-fed days with a reflection screen, up to 12 hours if necessary。
Iv. Fertilizer management (precision does not burn root)
- watering: under-film dripping is the main source of water; three to five days of indigence after planting and drying and wetting after seeding; and the flowering and chromosomal control of the water against fissures。
- fertilizers: - post-sapling: dripping high-phosphorus water soluble, promoting roots。
- right-to-east: high phosphorous is the main type, with boron fat and deformed。
- boiling to harvest: high potassium + calcium, once in 7-10 days, sugar, fibrous fruit。
- leaf spray: bouquets, ointments。
- avoidance of pits: no use of nitrogen, no use of fatty water, no use of flowers。
Plantation and flower fruit management
- plantation management: the timely removal of leaves, sick leaves and runners; the retention of 8 to 10 leaves per plant; and the removal of high-level curvature buds, each with 8 to 10 flowers。
- pollination: a bee is placed in the first flower and a bee is a bee; a bee box is placed 15 cm from the ground, towards the sun and avoids the bee's plaque。
- succeeding: deformation, insect fruit, quality fruit。
Vi. Green control of pests and pests (reduced medicine safety)
- diseases: - grey-stereotype diseases: high-precipitation, wet-control + pick-up of fragrances; first-time administration of cologne, americine, and careful use of flowers。
- powdery: leafback powder, ventilation, wetting; early administration of ethylene esters, paraquat sprouts。
- root diseases: soil disinfection before planting; rooting with a virulence。
- pests: - aphids/systroids: cedar aphids, blue aphids; fungus alkaline, ethylido fungi。
- red spiders: keep humidity; release dictums or use avil, biphenyl ester。
- principle: prevention takes precedence over life and safety intervals are strictly enforced。
Vii. Receiving and paying
- harvesting: 70 per cent of fruit flour is taken in red, 8-9 per cent in winter, 8-10 a. M. Or 4-6 p. M., with light grade。
- after-mining: clean up the debris of the shed, plough the tan and prepare for the downside。
Viii. A reminder for the northern region
- plantation: mid-august-early september, rooting with irigonin a+ meioamine, rooting against corruption, anthrax。
- control: set an appropriate amount of multi-activated accelerator after 20 days of planting, to control the master, to produce flowers。
- temperature: below 10°c at night. • vacuum membranes, hot stoves for extreme temperatures; temperature above 12°c。
