1 the planting period: early august-early september, mid-september. The country's vast territory, with different planting times in different regions, should be established early in the northern region, where it will be established in mid-august and mid-september as a popular agriculture。

2. Indensity of plant: 7,000 - 10,000 acres. (b) palladium: 0. 30 - 0. 35 m range and 0. 20 - 0. 30 m range per line per line per line; and high: 2 m range and 0. 25 - 0. 20 m range per line per line per line。
3. Plantation: the choice should be made to plant it after 4 p. M. Or 5 p. M. To avoid sunlight. Saplings should be planted with three to five leafs, with more than 10 new roots, full of disease-free seedlings. The depth of planting is the key to the survival of the seedlings, which, if planted too thinly, can lead to death. It is right to flatten the neck of the seedlings to the ground, to reach the unheard, to the shallow roots of the bows, and to allow the roots to extend to the full extent, to plant the soil, to pour water immediately after planting, and to pour water for three to four days. When water is poured, it is promptly checked and replanted as required. And when it has been set, if it comes to the sun, it shall be covered with reeds or branches of leaves。
Post-plantation: strawberries have a short reproductive cycle with high yields, combined with compost and water, which strengthens soil, fat and water-centred efforts。
X. Strawberry disease:
The main aggressions are on leaves and on the tip; flowers, fruit, infarction and leaf handles can also be harmed. (1) selection of disease resistant varieties. (2) cleaning of strawberries and a variety of weeds in clean sheds or fields, cleaning of orchards in winter and spring, burning of rotting leaves and timely removal of sick leaves during the growing season. (3) rationally dense planting, strengthening of fattening water, increasing the strength of plants, their own resistance to disease, and avoiding human transmission by avoiding as much as possible “coercion” between farmers. (4) prevent the application of nitrous fertilizers, control the masters, and be aware of the ventilation and the timely prevention of wetness after the rain. (5) discovery of the chicken, the fruit of the disease shall be removed lightly at the earliest possible time and shall be filled with a handbag to burn down or buried in depth (6) chemical: take possession of timely medication at the onset of the disease. Sulphur fumigation prevention techniques: the area where the unsatisfied strawberry varieties are fragrances, women's peaks, zhang jie and grumpy is still large is dominated by the health hazards of sulphur fumigation techniques. Sulphur fumigation technology consists of the installation of a fumigator at every 100 m2 in the shed, containing 20 g of sulfur powder and 99 per cent of that powder, which begins to heat fumigation after the curtains are covered in the shed in the evening. The following day, one for four hours each, is observed and is supplemented when the sulphur powder is insufficient. The fumigator hangs in the middle of the shed 1. 5 metres from the ground

In order to prevent sulfur gas scorching, an umbrella membrane can be installed at 1 m above the fumigator for the protection of the mural. This is not harmful to bees, but the fumigator temperature may not exceed 280°c in order to prevent the subsulphuric acid from causing a medical hazard to strawberries if the night temperature in the shed exceeds 20°c at a discretionary rate. Fifty per cent of the net suspension agent 600 times the fluid; 70 per cent of the tobuzine 1000 times the fluid available; 25 per cent of the stainful vinyl humid powder 3,000 to 5,000 times the fluid; 50 per cent of the debacterium 800 times the fluid and 30 per cent of the tufurin 5,000 times the fluid spray; 10 per cent of the high water dispersible granule agent 2000 to 2,500 times the fumes spray; 40 per cent of the huf 10,000 times the fluid; 12. 5 per cent of the americium emulsifiable cream 1,500 times the fluid; the fumigants 100 times the fumigation, fumes, which can be mixed; and every 7 to 10 days, multiple drugs can be used interchangeably to prevent resistance。
Eleven, the mantle is called the golden flower. It's the main pest that endangers strawberry. Insects and larvae both endanger the leaves, leaving irregular holes in the leaves after strawberry has been injured, and the heart leaves are eaten up and plant growth and development are affected when severe. It rises winter with adult insects within 5-10 centimetres of the ground and falling leaves. At the spring temperature of 10°c or more, the insects of winter come out of the soil, take leaves, lay eggs soon and hatch larvae。
(1) elimination of weeds in strawberry gardens, et cetera
(ii) removal of yellow leaves from the lower of the strawberry plant during the peak of spring spawning, burning, elimination of ovulations, insect sources
(3) pharmacist: 25 per cent of the micro-water suspension of thiophosphorus was sprayed 1,000 times during the infestation period。

Twelve. The tiger is known for its name. For insects. Strawberries with larvae, infrequent hazards of larvae of larvae of larvae of larvae above three years of age, smooth, gray, striped or tattooed, during the day or in the surface layer of 6-7 cm or above, in the evening or at night. They often cut off the new stammers of the grass, causing the whole body to die, eating leaves or eating fruit into holes. The higher the temperature, the greater the activity. Insects prefer to lay eggs on the back of wet or near-ground leaves and on many weeds and leaves such as eggplant and pepper。
: before planting, many shallow tillages and dredges were used to eliminate the earth's eggs. Remove weeds from the fields and concentrate on fattening or burning in order to eliminate grass-fed eggs and larvae. When leaves are found to be missing and dead seedlings are found, larvae are immediately dug up in the vicinity of the seedlings and concentrated in eradication。
Lice are the main pests protecting the ground strawberries, whose lobe uses juice on the back of the leaf, causing the leaf to fade, turn yellow, atrophy and, in serious cases, to die. At the same time, its nectar pollutes the leaves, breeds and affects their photocosm. Vegetable worms are 1. 0 ~ 1. 4 mm long, light, and their wings are covered with white wax powder. The eggs are 0. 2 mm, with a long circle, with a short ball handle, which is freshly lightened and the colours are increasing when hatching; if the insect is flat, elliptical, light or light green, there are five to six pairs of waxes on the back. Lice reproduce quickly, with more algebras occurring every year and overlapping over generations. It reproduces at a suitable temperature of 18°c ~ 21°c and completes a generation in about january。

(1) the induction of lice-based trends is carried out using 1. 00 m x 0. 17 m fibreboard or other hardboards, coated into oranges and then on top of them, scattered in greenhouses, with 32-34 pieces per acre, and booby-trapped into insects。
(2) the pharmaceutical agent uses 25% lice humid powder 2500 times more liquid, or 2. 5% kung fu cream 3,000 times more liquid spray。
What are the hazards of strawberry slashed night moths? What
Hazard characteristics: the risk of larvae being used to extract leaves leaves leaves only bare leaves in the event of serious damage。
In the case of larvae, pyrethroids or organophosphorus, e. G., pyrethroids, pyrethroids or organophosphorus, mainly in pharmacin, larvae, larvae and fluoride, during the ovary period, with regard to intervals and safety periods。
Fifteen. What about the damage to strawberries caused by the platinum

(1) the luminous character of the beetle is used to induce death with black light。
(ii) artificial capture: the plume prefers to make a waste of earth on the surface, where the worm nest can be found with traces, killing the insect。
(3) dispersion of bait: a 90 per cent 30-fold liquid of 150 ml, 5 kg of wheat accelerant or bean cake mixed with a smelting, with the application of the evening to the ground。
