The seedlings can withstand high temperature for a long time(plastic nursery plant pots manufacturers malaysia), benefit the soil by 1.5 ~ 2cm after sowing, 4500-7500g selected seeds for drill sowing, about 15kg seeds for sowing (per hectare), and cover the ground with shading net, straw curtain, wheat straw and straw for moisture after sowing to facilitate seedling emergence.

If it is dry after sowing, it shall be watered during seedling emergence, and it shall be watered continuously 2-3 times for summer sowing(13cm plastic plant pots). In order to sow evenly, the seeds can be mixed with fine sand, fine sand or plant ash before sowing. In order to remove weeds in the row before seedling emergence, Chinese cabbage or Chinese cabbage seeds with 2% seed amount shall be added(plastic nursery plant pots manufacturers malaysia). 


When the fleshy roots begin to expand, nitrogen and potassium fertilizer shall be applied(72 cell seedling trays). Their seedling emergence can show the location of carrot sowing row early, and they can also provide shade and heat protection for carrot seedlings during summer sowing. Carrot has long emergence time, dense seedlings, slow growth and growth speed, and is prone to grassland(200 cell trays). It must be weeded in time, and herbicides are more suitable(plastic nursery plant pots manufacturers malaysia).


Carrots sown in spring should be harvested when the average temperature of the day is above 25 ℃(plastic nursery plant pots manufacturers malaysia). The harvest time of autumn sowing is the same as that of Chinese cabbage. The yield per hectare is generally 22500 ~ 75000 kg, which should be buried in time after harvest(105 cell plug trays). At the end of this period, the main root can reach 60cm, the lateral root can reach 10 ~ 35cm, and the suitable soil relative water content is 85% ~ 90%.


Autumn sowing shall be determined according to different varieties and regions. If the shoot grows, spray it with 150 times of 15% Paclobutrazol wet powder, which can promote the expansion of fleshy root arms. Topdressing 2 ~ 3 times. The sowing date of cultivation technology shall be determined according to the time of harvest and listing in spring(50 deep cell plug trays). Generally, it shall be sown as early as possible(plastic nursery plant pots manufacturers malaysia). 


Storage resistance was related to carrot color(32 cell plug tray). The order of storage resistance from strong to weak was orange > purple > Orange > yellow > red. Northern varieties are more resistant to storage than southern varieties. Generally, the optimum temperature for stem and leaf growth is 23 ~ 25 ℃, leaving only the main stem for seed collection, and the seed yield is low(plastic nursery plant pots manufacturers malaysia). The germination period is from seed germination to true leaf exposure.


However, the carrot planted has high yield, and the main diseases and pests include black rot, Sclerotinia, soft rot. aphids, fennel butterflies and other vegetables are the most important vegetable species in China(32 cell seedling tray). Therefore, its planting area and yield rank first among all kinds of vegetables in China(plastic nursery plant pots manufacturers malaysia). It has the advantages of easy cultivation, high yield, transportation resistance It has the advantages of low price and various food methods.


Planting in spring, open field seed collection, isolation of more than 2000 meters(128 cell seed trays). Chinese cabbage is the most important vegetable in autumn, winter and early spring in the north(plastic nursery plant pots manufacturers malaysia). The vegetative growth stage is divided into germination stage, young bacteria stage, rosette stage, heading stage and dormancy stage, and the reproductive growth stage is divided into twilight stage, flowering stage and English setting stage. 


In the late stage of the rosette stage, the heart leaves hold life, which is called "rolling heart"(50 cell plug trays). Early maturing varieties with heat resistance, waterlogging resistance and high temperature nodulation should be selected for cultivation in summer(plastic nursery plant pots manufacturers malaysia). Growth and development period and requirements for environmental conditions the growth of vegetables can be divided into vegetative growth stage and reproductive growth stage. 


When the disease is serious or the previous crop is difficult to turn flowers, early maturing varieties suitable for local eating habits and storage can be selected for late sowing(7 gallon pots). It germinates rapidly at about 25. At this stage, the radicle can reach more than 10cm, but there are few root hairs, no lateral roots, and the water absorption is very weak(plastic nursery plant pots manufacturers malaysia). The soil is required to be wet and suitable for 90% of the relative soil water content.


The suitable temperature is 17 ~ 22 ℃. It takes 15 ~ 20 days for early maturing varieties and 25 ~ 28 days for medium and late maturing varieties(10cm plastic plant pots). Sensitive to nitrogen, slow growth when lacking, when nitrogen, phosphorus, potassium deficiency, disease resistance decreased(plastic nursery plant pots manufacturers malaysia). In the late stage of rosette stage, the outer leaves formed the most, the leaf area increased the fastest, and the bulb leaves differentiated rapidly.


It can be sown for 2 days at an appropriate temperature, and the germination period takes 5 ~ 6 days(5 gallon pots). At the stage of rosette, the main root did not continue to elongate, but the lateral root was quite developed, and the lateral root 6 ~ 30 cm below the soil surface was the most developed(plastic nursery plant pots manufacturers malaysia). At this stage, the photosynthetic intensity was high(128 cell trays). The suitable temperature for growth is 15 ~ 22c during the day and 5 ~ 12 ℃ at night.


The balling stage is from the beginning of the heart lobe to the formation of the leaf bulb(plastic nursery plant pots manufacturers malaysia). The suitable temperature for growth is 12 ~ 16 ℃. The flowering period is from flowering to the end of flowering, which generally takes about 30 days(162 cell plug tray). Before sowing, 1500 ~ 2250 ml of 48% trifluralin emulsifiable concentrate or 3 ml of deltame emulsifiable concentrate shall be used per hectare (000 ml, spray treatment of soil.


It takes 25 ~ 30 days for early maturing varieties and 30 ~ 50 days for medium and late maturing varieties. The growth at this stage accounts for about 70% of the total plant growth, and the suitable relative humidity is 80% - 90%(72 cell plug trays). The fleshy roots with neat and smooth shape, consistent thickness from top to bottom, few leaves, small stem disc and color in line with the characteristics of varieties shall be selected for seed storage(plastic nursery plant pots manufacturers malaysia).


The suitable temperature for seed germination is 20 ~ 25 ℃, and the dormancy period is forced into dormancy due to the cold climate. At this time, flower buds and young flower buds continue to form(plastic nursery plant pots manufacturers malaysia). At dusk stage, the plant grows slowly from flower buds and young flower buds to flowering(200 cell plug trays). The optimum growth temperature is 18-20 ℃, and the seed plant continues to branch to the maximum plant shape.


Generally lower than 15 ℃ or higher than 25 ℃ is not conducive to seed formation(14 cm plastic plant pots). Chinese cabbage can recover its growth under a short-term low temperature of 2 ~ - 5 ℃, but it can not tolerate a low temperature below - 2 ℃ for a long time(plastic nursery plant pots manufacturers malaysia). Sufficient sunlight is required, and low illumination seriously affects the output(105 cell plant trays). Low temperature and long sunshine are conducive to bud formation, flowering and fruiting. 


Seeds germinate, generally 2-10 degrees, 10-15 days can be completed vernalization, autumn cultivation generally do not draw, and spring cultivation is adorable(seedling tray 104 holes). It requires high air humidity. The suitable soil relative water content is 75% ~ 85%. After spraying, mix ten 1-5cm, and then sow(plastic nursery plant pots manufacturers malaysia). The rosette stage is from the closing of the tree to the full expansion and rapid expansion of the 23rd-25th rosette leaves.
