Bolting is the production of a flowering stem (or stems) on agricultural and horticultural crops before the crop is harvested, in a natural attempt to produce seeds and reproduce. These flowering stems are usually vigorous extensions of existing leaf-bearing stems, and in order to produce them, a plant diverts resources away from producing the edible parts such as leaves or roots, resulting in a poor quality harvest. Plants that have produced flowering stems in this way are said to have bolted. Crops inclined to bolt include lettuce, basil, beetroot, brassicas, spinach, celery, onion, and leek.

InactiveCN101897308AEasy to collectQuick collectionClimate change adaptationPisciculture and aquariaGlass fiberEngineering
The invention relates to equipment and a method for collecting industrially cultivated pelagic eggs. The equipment comprises a water inlet tube, a drainage tube, an anti-flow drainage tube, a glass fiber reinforced plastic groove and a pelagic egg collecting net cage. The use method of the equipment comprises the following steps that water for cultivation flows into a cultivation pool through the water inlet tube to form a gentle water surface circumfluence; and the pelagic eggs are driven to be discharged into the pelagic egg collecting net cage outside the pool through the drainage tube. The mesh of the pelagic egg collecting net cage is bolting-silk of 260-300 meshes and is located in the glass fiber reinforced plastic groove. The pelagic eggs are blocked by the mesh and collected in the net cage while water is discharged through the drainage tube of the glass fiber reinforced plastic groove. In order to prevent overflow of water in the cultivation pool, an anti-flow drainage tube is arranged close to the drainage tube in the cultivation pool. The tube orifice in the pool is higher than the water level of the pool but lower than the maximum height of the pool wall. The tube orifice outside the pool is located in the pelagic egg collecting net cage. Shown by practices, the invention can rapidly and effectively collect the pelagic eggs in the collecting pool and has the advantages of small mechanical damage to eggs in the collecting process and high collecting efficiency which reaches above 95% and low facility improvement cost and easy popularization.
