For fruits and vegetables cultivated in long seasons, the main characteristics are as follows(plastic terracotta pots wholesale price australia): in addition to the rainproof shed, it can generally realize semi closed or closed environmental regulation, which is conducive to creating the most suitable environmental conditions above and below the ground of vegetable crops and realizing high quality and high yield. The multiple cropping index is high.

Vegetable protected cultivation is a high-tech, efficient and intensive agricultural technology(plastic plant pots wholesale australia). Due to perennial shelter from rain and long-term thermal insulation or heating in winter, fine and intensive management technology is required for soil moisture management, ventilation, heating and thermal insulation in winter and prevention of heat accumulation in summer(plastic terracotta pots wholesale price australia). Seedlings are cultivated in hotbeds or heated.
The percentage of sunshine in this area in January is below 45%(128 cell seedling trays). Such as tomato and cucumber, how to maintain the balance between vegetative growth and reproductive growth has become the key of cultivation technology(plastic ground cover for weed control). The environmental regulation, production period regulation and out of season cultivation of protected vegetables require a lot of labor, and labor-saving techniques should be adopted as far as possible(plastic terracotta pots wholesale price australia).
A certain vegetable production facility in this area still mainly uses various types of plastic sheds in early spring and late autumn(plastic terracotta pots wholesale price australia). Facilitating cultivation, also known as overwintering cultivation, deep winter cultivation and long season cultivation in winter and spring, refers to the cultivation method of long-term heating or heat preservation by using greenhouse and other facilities in severe cold season in winter(40 cell seed trays). It is cultivated in a large plastic greenhouse.
It is difficult to pollinate and fertilize in the low-temperature period of protected fruit and vegetable cultivation(8 cell plug trays). Such as September to June of the next year, October to June of the next year, etc(plastic terracotta pots wholesale price australia). From the current extensive production practice of rapid propagation of test tube seedlings, the vast majority of the tested test tube seedlings in the total area of protected horticulture in China are protected cultivation of vegetables.
Delayed cultivation in autumn generally refers to the delayed cultivation of thermophilic vegetables(105 cell propagation trays). In the early autumn, it grows in uncovered sheds or in the open field. Before the arrival of early frost in late autumn, the film is buckled to prevent frost and semi facilitated cultivation(plastic terracotta pots wholesale price australia). It is the coldest climate zone in my country(11 cm plant pots). Facility production, mainly in solar greenhouses in winter, with temporary heating equipment.
Early maturing cultivation refers to colonization under facility conditions, short-term heating in the early growth stage and no heating in the later stage(6 cell seed trays), The cultivation method of early listing in spring is only to keep warm or change to open ground to continue to grow or harvest(heavy duty 1020 trays). It requires the use of modern cultivation management and management technology in order to achieve the goal of high input and high yield(plastic terracotta pots wholesale price australia).
Summer cultivation is the main type of cultivation in summer using shade nets, insect nets, and rain rent in the vast areas south of the Yangtze River(19cm plastic plant pot). The supply period is 1 ~ 2 months later than that of open land(plastic terracotta pots wholesale price australia). Protected vegetables can be produced throughout the year, and suitable ecological varieties should be selected in different seasons to adapt to different climatic environment and prevent growth obstacles.
Inhibition cultivation (delayed cultivation)(72 cell tray). The division of greenhouse vegetable cultivation in China is equal to the main stubble form(plastic terracotta pots wholesale price australia). In order to prevent flower and fruit falling, hormone should be avoided as far as possible, and labor-saving and environment-friendly agricultural technologies such as pollination by bumblebees and other insects or selection of varieties with strong parthenocarpy should be used.
They are planted from early April to early May, and harvesting begins in early June(128 cell plug flats). Greenhouse vegetable in China is divided into the following four climate regions(plastic terracotta pots wholesale price australia). The temperate climate zones of Northeast China and new North Mongolia are located in the north of the Great Wall, north of the - 10 ℃ isotherm of the coldest climate in the year, Heilongjiang, Jilin(36 cell seed trays), Liaoning, Inner Mongolia, Xinjiang and other places.
Under closed environmental regulation conditions, biological technologies such as natural enemies can be used to prevent pests and diseases, and pesticide-free or low-pesticide cultivation can be implemented(plastic terracotta pots wholesale price australia); the cultivation season of facility vegetables is long(4 cell seed starting trays), and the monthly average sunshine hours in January is 180~200 hours, and the sunshine percentage is 60%. ~70%, the average temperature in January is lower than -10℃, and the lowest in the north reaches -20~-30℃.
At this time, the teaching and training forms and crops of the hat room facilities mainly include(20 cell seed trays): solar greenhouse cultivation in autumn and winter, sowing from July to B, planting in early September, and harvesting from mid-October to November(plastic terracotta pots wholesale price australia). Early spring lotus cultivation in the solar greenhouse, using hotbeds or warming seedlings, planting from mid-February to early March, and pulling seedlings in late July(112 cell plug trays).
Various types of plastic pots can be used in the production of spring and autumn vegetables, but attention should be paid to cold and wind protection(plastic terracotta pots wholesale price australia). In general, cover the Suyang net on the large phase frame or remove the mask of the big orange, only keep the top film and cover the Yiyang net(plastic hanging baskets wholesale), and use the summer facility training technology to reduce the temperature of the sun, prevent rainstorm and combine wind.
The climate zone of the North China Warm Zone includes Qinling, the north of the Nanhe River, the south of the Great Wall, the coldest iron temperature -10℃ isotherm to the south, 0℃ isotherm to the north, Beijing, Tianjin, Hebei, Shandong, Henan, Shanxi, Shaanxi South of the Great Wall to the north of the Qinghe Plain(18 cell seed trays), as well as Gansu, Qinghai, Tibet, and northern Jiangsu, Anhui, and the Liaodong Peninsula(plastic terracotta pots wholesale price australia).
The area has sufficient sunlight in winter and spring and is a climate-friendly area for vegetable production in solar greenhouses in my country(plastic ground cover). General shed facilities cut cultivation forms and crops mainly include(plastic terracotta pots wholesale price australia): sunlight greenhouse or modern greenhouse early spring shoes, autumn and winter stubble, winter and spring stubble: plastic arch sugar (Dati, Zhongfu) early spring and late autumn cultivation(fabric smart pots).
As urban agriculture, modern heating greenhouses can be appropriately developed in the suburbs of large and medium-sized cities to produce vegetables, flowers, and fruits with high added value(plastic terracotta pots wholesale price australia). Gardening products(12 cell seed trays). According to the form of increase in facilities and crops, the main types of crops are as follows: facilities are mainly used for cutting and training, and summer is mainly covered by Suyang nets and insect-proof nets.
Among them(50 cell seed trays), Sichuan Basin and Guizhou The provinces and western Hunan and southwestern regions have the lowest percentage of sunshine in January in the whole country, all of which are below 20%, and the subordinate ministries are below 15%(plastic terracotta pots wholesale price australia).
