Die tydige vooruitbeplanning van al die take wat in die board gedoen moet word, is noodsaaklik. Die doel van hierdie seisoengids is om die produsent in staat le stel om vooruit te beplan en al die nodige voorbereidings te tref om die spesifieke take op die regte tye uit te voer. Hierdie vereenvoudigde seisoengids gee ‘n aanduiding van elke taak wat gedurende ‘n sekere periode aandag moet geniet. Dit moet gebruik word saam met die voorskrifte wat volledig in die onderskeie bladskrifte uiteengesit word. Tye mag tot ‘n mate verskil in die verskillende klimaatsgebiede waar lietsjies verbou word.
Summary:
- The guide is designed to help lychee producers plan all orchard tasks timely to ensure proper execution.
- It provides a simplified seasonal calendar indicating key tasks throughout the year, helping producers prepare for specific activities at the right time.
- The tasks include soil sampling, soil preparation, planting in the orchard, leaf sampling, fertilization (nitrogen, phosphorus, potassium, micronutrients), irrigation, weed control, and purchasing and applying protective paper bags.
- There is emphasis on controlling fruit fly through bait sprays and the use of paper bags on fruit clusters for protection.
- Harvesting lychee fruit when the mass reaches about 19 grams is noted.
- Other horticultural practices covered are pruning young trees, reproduction through seed and plant material, ring barking, and grafting.
- The calendar shows the approximate months when each task should be done; however, exact timing can vary with different climate regions where lychees are grown.
- Additional activities include making and pruning air layers and nursery cuttings.
- The guide recommends using this seasonal calendar alongside detailed prescription sheets found in accompanying documents.
- The overall goal is to facilitate advance planning and execution of lychee orchard practices for optimal production.
