Frozen fruit breeding periods are environmentally demanding, and suitable shed construction can be effective in increasing the success rate. The following are the key steps and concerns in the construction of the flamingo nursery, which helped growers to build nursery facilities in science。
I. Site selection and building specifications
1. Site selection criteria: selection of flat, well-drained, soil-rich plots away from sources of pollution. It is recommended that the spacing of the shed be maintained at more than 2 metres to avoid the impact of the shade。
Type of shed: priority is given to steel frame structures or bamboo skeleton sheds with strong wind resistance. The range is generally 6-8 metres, with shoulders of 1. 5-1. 8 metres and tops of 2. 5-3 metres, and the length is determined by the size of the nursery (recommendation 30-50 metres is appropriate)。
Infrastructure and facility configuration
1. Soil improvement: the seedling matrix needs to be ablaze and can be used as a base for grass-breeding soil: coconut quarries: pearl rock = 3:2:1, mixed with 500 kg of decomposition organic fertilizer per acre。
2. Temperature control systems: installation of vents, water curtains and sunnets that can cool in the summer with ventilation and temperature control at 25-35°c. Temporary heating equipment (e. G., fuel heater) is required for winter。
3. Irrigation systems: the use of drip irrigation or spraying to ensure even water supply. Slender beds are equipped with a network of spray pipes that maintain air humidity at 60-80 per cent。
Iii. Management of seedlings and maintenance of sheds
1. The selection of seedlings: the choice is to plant them 15 to 20 cm in length with a strong pyroclastic pyramid, free of pests and diseases, and dry them for 1-2 days。
2. Environmental regulation: avoiding strong direct light during seedlings and keeping the luminous net luminescence at around 50 per cent; maintaining soil moisture during root periods and timely spraying and humidification when air moisture is below 60 per cent。
3. Garbage maintenance: periodic inspection of the structure of the steel frame for rust resistance, during the rainy season, with attention to drainage and avoiding the accumulation of water at its roots. Every spring, the aging sunshad net and the wormnet are replaced。
Iv. Cost-budget and benefit analysis
1. Cost reference: the simple bamboo huts cost approximately $15-$2,000 per acre and steel sheds 30,000-$40,000 per acre (including infrastructure, irrigation and temperature control equipment)。
2. Comparison of benefits: the science nursery can increase the rate of seedlings to more than 90 per cent, with a combined economic benefit two to three months ahead of field seedlings。
The construction of reasonable huts is the foundation for the success of the flames. It is recommended that growers adapt their programmes to local climatic characteristics and the size of their seedlings, while improving their productivity with modern management techniques. More details can be obtained from local agricultural technical departments for targeted guidance。
