Como cultivar lettuce lollo bionda?

Um guia de cultivo passo a passo, da sementeira à colheita.

pH ideal 5.5 and 7Temperatura ideal 20 and 30°C

Sementeira

Sow in trays and transplant seedlings to their final location 3 to 4 weeks later. The crop can be grown in rows, with 15 to 20 cm between plants and 45 to 60 cm between rows.

Solo

It is a crop that adapts well to different soil types, though it is essential that they have good drainage capacity. Soil pH should be between 5.5 and 7.

Clima

The crop prefers temperatures between 20 and 30°C; however, temperatures should not be extreme, as they will cause premature bolting.

Fertilização

Compost should be incorporated into the base fertilization to meet the crop's nutrient requirements. It is important that the soil has adequate phosphorus at the start of development; if sufficient levels are not present in the soil even after incorporating compost, a mineral fertilizer rich in this nutrient should be added.

Rega

Watering should be frequent since the root system is not very deep. Drip irrigation is particularly well-suited for lettuce cultivation, as it prevents excessive moisture on the leaves and thus reduces the risk of disease.

Controlo de Infestantes

Mulching is an interesting option for lettuce cultivation, reducing competition between weeds and the crop.

Controlo de Pragas

Mites, aphids, leaf-miner larvae and root-knot nematodes are pests of this crop. Mite control can be achieved through biological control with predatory mites and, if necessary, by applying azadirachtin or sulphur dust (if T < 28°C). Aphids can be controlled through moderate fertilisation without excess nitrogen, natural limitation using border hedgerows to support beneficial insects, biological control with parasitoid and predatory Hymenoptera and, if necessary, application of potassium soap or azadirachtin. Leaf-miner larvae can be controlled through natural limitation with hedgerows and other vegetation containing nectar plants that feed adult parasitoids, biological control with parasitoid Hymenoptera and, as a complementary measure, application of azadirachtin. Root-knot nematodes are controlled through crop rotation, biofumigation and soil solarisation.

Doenças

Alternaria leaf spot, sclerotinia, downy mildew and grey mould are diseases affecting this crop. To control alternaria, wide plant spacing and copper-based fungicides (such as Bordeaux mixture) should be used. To control sclerotinia, appropriate crop rotations and wider spacing should be practiced, and infected plants should be removed from the field as early as possible. Downy mildew can be controlled through crop rotations of at least 3 years, avoiding excess soil moisture and air humidity, using wide spacing and, if necessary, applying copper hydroxide at reduced concentrations (which should be lower the colder the weather, as it may cause leaf scorch). Finally, grey mould should be controlled by removing diseased plant debris, avoiding excessive vigour, keeping water off the plants and applying bentonite clay regularly.
