Hyacinth bulbs usually develop within the open floor. Consequently, fertilizers could leach into the floor water. As well as, the bulbs are vulnerable to soil-borne ailments and pests (akin to fungi and nematodes). Analysis by the Greenhouse Horticulture and Flower Bulbs Enterprise Unit of Wageningen College & Analysis reveals that the bulbs may also be grown nicely in plastic trenches.
The Bollencoaster venture is geared toward making bulb cultivation extra sustainable. One of many parts is analysis into the usage of plastic slots. These are buried within the discipline at a depth of 10 to twenty centimeters and with a width of roughly 5 centimeters. There’s a drip hose within the trench for watering and administering vitamins. The highest of the ditch is closed in order that ailments, pests, and undesirable water can’t penetrate. Within the trench, the bulbs are planted on a substrate.
This cultivation technique has many benefits within the cultivation of hyacinth. This makes focused watering doable, and there’s no leaching of water and fertilizers. As well as, fewer crop safety brokers are required. The slits enable the bulbs to develop in a protracted row, which facilitates mechanical weed management. As a result of the bulbs don’t develop within the floor, fungi, and nematodes can’t have an effect on the crop. Crop rotation is subsequently not essential (in typical crops, hyacinths can solely develop on the identical soil as soon as each six years). Consequently, growers wouldn’t have to search for a brand new discipline yearly. And most significantly, the bulbs develop nicely in an enclosed setting.
There are additionally disadvantages and factors of consideration. For instance, the soil within the trench will need to have ample vitamin and be clear. This may be achieved by utilizing new substrates throughout every cultivation spherical, akin to coconut peat substrates. Another is to make use of the sand within the discipline. Nonetheless, this should first be steamed and presumably supplied with biostimulants. As well as, the grower should spend money on, amongst different issues, the plastic slots and the drip system. The highest of the ditch typically seems to open, permitting rainwater to enter the ditch, for instance. As well as, it must be prevented the soil across the trenches turns into impoverished: it would subsequently be sensible to let one thing else develop, for instance, grass, between the hyacinths.
The analysis into hyacinth takes place at Agrifirm-GMN in Voorhout. In the identical discipline, a examine of lilies is being carried out (each crops alternate in spring and autumn). Analysis can also be being carried out on the WUR analysis location in Bleiswijk into the potential for additionally cultivating different flower bulbs on this system, akin to tulips, gladiolus, and zantedeschia.
Bollencoaster is a four-year analysis program of the Horticulture & Propagation Supplies prime sector of the Ministry of Agriculture, Nature, and Meals High quality. The implementation of this Public-Non-public Partnership is the duty of a consortium of seven companions. These are: KAVB, Agrifirm-GMN, Oerlemans Plastics, Rabobank Bollenstreek, Hoogheemraadschap Rijnland, Greenport Duin & Bollenstreek and Wageningen College & Analysis.
