Novel technology for precision cultivation and advanced harvest of eggplants in southern China in open ground

Abstract

The invention discloses a novel technology for the precision cultivation and advanced harvest of eggplants in southern China in open ground. Healthy eggplants grown in autumn are adopted in the technology; when the in-season harvest is terminated, the eggplants pass the winter in a big field naturally; when the temperature starts to rise from mid-to-end of February in the next year, old eggplant trees are trimmed; the eggplants are cut off from 2-3cm down from the simendou eggplant growing positions, and 4 trunks are left for each eggplant. Eggplant products can be put into the market in early April in advance, while the harvest period is one-month longer than the traditional cultivation, the production cost is reduced by RMB1000 / mu, the eggplant products are put into the market 30 days earlier than traditional eggplants grown in spring, so that 1200kg / mu can be harvested in advance in terms of RMB8 / kg, the economic benefit can be increased by RMB9600 / mu, and the revenue / expenditure of RMB10600 / mu can be increased / reduced in total, with a considerable benefit.

Description

technical field [0001] The invention belongs to the technical field of eggplant cultivation, in particular to a new technology for early harvesting of eggplant in open fields in South China. Background technique [0002] At present, the technologies for planting eggplant in production are as follows. The high-yield cultivation technology of perennial eggplant is adopted in North China, mainly in greenhouse cultivation in autumn and winter. Plant it in the open field where eggplant has never been planted, and germinate hidden buds. When the weather turns cold in November, then transplant it into a greenhouse to achieve multi-year production. , time-consuming and labor-intensive, and high cost; Hainan takes advantage of its geographical advantages, the temperature is high in winter, the plants grow normally in winter and spring, and eggplants are planted out of season. Freshness, when the temperature rises, the benefit of planting eggplant will be significantly reduced; the o...

[0002] At present, the technologies for planting eggplant in production are as follows. The high-yield cultivation technology of perennial eggplant is adopted in North China, mainly in greenhouse cultivation in autumn and winter. Plant it in the open field where eggplant has never been planted, and germinate hidden buds. When the weather turns cold in November, then transplant it into a greenhouse to achieve multi-year production. , time-consuming and labor-intensive, and high cost; Hainan takes advantage of its geographical advantages, the temperature is high in winter, the plants grow normally in winter and spring, and eggplants are planted out of season. Freshness, when the temperature rises, the benefit of planting eggplant will be significantly reduced; the open-field cultivation technique of spring eggplant currently widely used in Guangdong is mainly to raise seedlings early in the seedling shed, and transplant them to the field when the temperature is suitable in March. Eggplants are ready to go on the market. This kind of cultivation method is to prepare the environment for facility seedlings to resist the cold of the seedlings in early spring, and also to carry out the process of transplanting seedlings. With the large number of other vegetable products on the market, the price of eggplants on the market will drop rapidly
