The so-called counter season vegetable is to avoid the normal cultivation season and market supply period of vegetables and adopt special cultivation techniques to cultivate vegetables(plastic terracotta pots). That is to say, 5000-7500kg of high-quality organic fertilizer can be applied to each mu of greenhouse soil, and 75-100kg of imported compound fertilizer (n: P2O5: K2O = 15:15:15) can also be applied to each mu without high-quality farmyard fertilizer(200 cell seedling trays).

For example, cabbage, cauliflower and other shade resistant vegetables cultivated in autumn are planted in spring and summer by covering sunshade net and cooling(cheap plastic plant pots bulk); cabbage, eggplant, melon and other vegetables planted in spring and summer are planted in greenhouse or plastic greenhouse(32 cell seedling tray). Supply market in four seasons, so as to improve the economic benefits of planting vegetables, so as to reduce the continuous accumulation of salt in the soil.


(cheap plastic 7 gallon container manufacturers china)Because it is an off-season vegetable, there are certain requirements for fertilizer application(black plastic plant pots). For heavy application of organic fertilizer, select the mature organic fertilizer as the base fertilizer one month ahead of the canopy, and put it into the greenhouse soil, the application amount is generally 1-1.5 times of the vegetable field cultivation(50 deep cell plug trays). The remaining nitrogen fertilizer is used as top dressing, and is applied in stages at the peak of vegetable growth.


According to different vegetables, the reasonable ratio of nitrogen, phosphorus and potassium was determined, and the corresponding microelement fertilizer was supplemented according to the demand of different kinds of vegetables(nursery plant pots). If chicken manure or cake fertilizer is applied to the base fertilizer, it shall be fermented and decomposed in advance(72 cell seedling trays). The heavy ones caused the dehydrated fertilizer damage to the seedlings of the anti season vegetables.(cheap plastic 7 gallon container manufacturers china)


It is strictly prohibited to pile up large amount of organic fertilizer in the shed for a long time to avoid damaging vegetables by toxic and harmful substances decomposed by fermentation(72 cell seed trays). If the water content of the greenhouse soil is insufficient, the fertilizer concentration in the greenhouse soil will be large, which will cause the water reverse osmosis in the vegetable cell, and cause the dehydration of the vegetable, and often make the vegetable wilt(162 cell plug tray).


(cheap plastic 7 gallon container manufacturers china)Provide sufficient nutrients for the growth of vegetables(growing trays). In particular, the application of chicken manure should pay special attention to prevent burning roots and seedlings(perlite). In order to avoid the harm of high salinity to the vegetables growing in the opposite season, the organic fertilizer and inorganic fertilizer can be used together, but the amount and concentration of chemical fertilizer should not be too much.


Generally, for vegetables with short growth period or with roots, stems and leaves as harvest, 1 / 3-1 / 2 of nitrogen fertilizer can be used, and all of phosphorus, potassium and micro fertilizer can be used as base fertilizer(seed starting trays). However, 1 / 3 of nitrogen, 2 / 3 of phosphorus and potassium, and all micro fertilizers can be used as base fertilizer, while the rest of nitrogen, phosphorus and potassium can be used as top-up fertilizer(200 cell plug trays).


In general, to prevent the anti season vegetables from growing in the greenhouses or greenhouses, the salt concentration of the soil in the greenhouses will increase because of excessive fertilization and no natural precipitation(15 gallon pot). Therefore, when applying fertilizer, we must adopt standardized application method, determine the proportion of organic fertilizer and chemical fertilizer, and try to take out a part of fertilizer for foliar spraying(128 cell seedling trays).
