In general, yam is not a continuous crop, and the land where the yam is grown needs to fall for three years(plastic nursery pots). The yam colonization is generally suitable in the middle of April, and should not exceed May. Open 10cm shallow ditch on the ridge, the yam plant is placed along the ditch parallel to the ditch(105 cell propagation trays wholesale), the bud is upward, the bud spacing (plant spacing) is 10~20cm, the ravine width is 70~90cm, and the topsoil is about 10cm.

Studies have shown that the yield of yam is the best when the plant spacing is 20cm and the row spacing is 80cm(plastic nursery pots wholesale). The dryness and wetness of the soil to be covered in the production is slightly dry on the surface soil, and the soil layer is preferably wet after the surface soil is removed by hand(50 cell propagation trays wholesale). When special topdressing, try to stay away from the yam plants, usually in the middle of two lines to avoid burning roots.(cheap 1 gallon fabric pots wholesale supplier)
Yam entered the sapling stage in mid-June(black plastic nursery pots). At this time, it was necessary to concentrate a single water to meet the development of shoots and shoots and the development of underground tubers(72 cell propagation trays wholesale). After the yam enters the upper part of the development period until the buds (about the end of July ~ early August), the water is replenished once to ensure the rapid development of the demand for water in the lower part of the tubers.
During the period, you should always pay attention to flood control and real-time drainage, otherwise large-scale production will be reduced(cell trays). After one month, depending on the specific situation, the water can be replenished to facilitate tuber enlargement. The study believes that yam should be topdressed 2 to 3 times during the growth period(98 cell propagation trays wholesale). The topdressing period is generally concentrated in the middle of June, from late July to early August, from late August to early September.
(cheap 1 gallon fabric pots wholesale supplier)Control method: The principle of watering is “do not dry or not”(plastic nursery pots manufacturers). When the vines grow to about 20cm, the “people” frame should be used for climbing development in order to avoid excessive madness in the upper part of yam. In the middle and late months(128 cell propagation trays wholesale), 15% paclobutrazol 60~70g and 60kg of water were stopped for spraying every 667m2 to promote the transfer of above-ground nutrients to the underground.
When framing, you should pay attention to the part of bamboo stalks that is far away from the yam plants to prevent damage to the roots(wholesale nursery pots). During the growth period of yam, weeding should be carried out in real time to avoid competition with plants for nutrients. When removing weeds in yam gully, we should pay attention to avoiding yam plants(162 cell propagation trays wholesale), avoiding the main stem of yam being cut off, and planting yam in large areas.
It is better to choose fine bamboo rafts for frame materials(21 cell propagation trays wholesale). If the grass is seriously damaged, Spray the appropriate herbicide (eg, Cao Cao Tong, Kuai) after the yam colonization. Strengthen cultivation management, planting density should be appropriate, not too dense, try to reduce the humidity inside the shed to prevent moisture retention(200 cell propagation trays wholesale). The drug was stopped 3 days before harvesting, and sprayed every 5-7 days for 2-3 times.
Generally, when the core is started, 65% of the sensible zinc wettable powder 600 times(32 cell propagation trays wholesale), or 70% of the mancozeb WP 500 times, and 2-3 years of rotation with the non-composite crops. First plant the seedlings and then pour the water, apply enough organic fertilizer, increase the application of phosphorus and potassium fertilizer, and improve the host's disease resistance(112 cell propagation trays wholesale). The medication was stopped 5 days before harvesting.(cheap 1 gallon fabric pots wholesale supplier)
