Dutch method of chrysanthemum farming
In the netherlands, the chrysanthemum breeds a well-soiled, ventilated environment and a fertile, well-drained sandy frontier. Half-monthly fertilisations are performed once a month and in the summers, causing multiple branches and flowers to bloom, but it is not appropriate to be too dense to plant plants, otherwise they are prone to white powder。
It is common practice to sow or divide reproduction, with a small number of adhesive reproductions。
1. Dutch hare seeding
The planting period is around early march. It's warm in the greenhouses and it's in the sun. Under conditions of room temperature of about 15°c, the seedlings are available for about seven days. The first split was done in time to avoid longings. It is possible to choose a 12-cm basin or plant it in a plume. In early may, a second split planting was carried out, either in large basins or directly, as required. The plant is contained at a distance of about 40 cm to facilitate its further growth。
2. The reproduction of the dutch chrysanthemum
The netherlands has a strong capacity for chrysanthemum, and separate strains can be isolated. The break-up time is generally chosen to unfrozen the soil in the early spring, and the mother plant has just grown leaves. The ground roots of the winters were dug, the pieces were cut into pieces with a knife and planted separately, with a very high rate of survival. This method can be used to produce large numbers of plants over the years。
3. Dutch haliform reproduction
Many years of growing plants have grown in large numbers after spring. A knife can be used to cut down the small saplings. The matrix is made of solute or pearl rock, cylindrical, at temperatures above 20 °c, which require shade or full-light spray devices to maintain air moisture, which can take root in about six months. Rooted plants can be installed directly into the basin or in the ground。
4. Dutch chrysanthesis
The use of wild artemisinin as a wood for indoctrination is more effective. By the end of november or the beginning of december, dutch aristocrats were removed from the bushes and turned over to the ground. When the outdoor temperature is reduced to about 5°c, the basin is moved into a cryogenic chamber, which is not allowed into a medium temperature or a high temperature room, so as not to draw a bud long enough to weaken the pyres。
Netherlands pest management
Powder and brown spots are common ... 65 per cent of the tobuzin humid powder can be sprayed 600 times. When aphids are in danger... 50% of dichlorvos cream is sprayed 1,000 times。
The main diseases of the platinum are leaf disease, yellow disease, fungi nuclei disease, powder disease and rusty disease, so that the soil should be decontaminated before the field is prepared. The main pests that harm the pyrethroids are underground pests and night moths. Underground pests, such as thionphos-methyl or trisulphage, were treated throughout the land, and in late september, such pests as slashed night moths were treated with agrolaga fungus. Powder and brown spots are common. Sixty-five per cent of the tobuzin humid powder can be sprayed 600 times. Aphid hazard. Killed with 50 per cent of the enebrane cream 1,000 times the fluid。
