High white winter production

The development of aquatic vegetables such as wolfberry white has been rapid, and some free flood lands, shallow ponds, especially some low-lying fields, have been planted on white, and planting white rice has become a good way for farmers to increase income. However, most farmers do not attach importance to management, and in particular do not pay attention to post-harvest management. Reasonably, the winter planting fields in Putian will have light pests and diseases in the coming year, with neat crop emergence, many tillers, thick seedlings, few grey plants and male plants, and high yield and high quality.

After clearing the white fields of Putian, we should promptly excavate the plants of the ashes and maggots in the fields, and cut the old leaves of the old plants on the old quagmire piers. The old leaves of the old plants will be piled together and burned. This will reduce the number of overwintering pests and diseases, and the buds will be neatly cut, and the new seedlings grown in the second year will be thick.

After harvesting in the dry field, the plants gradually entered a dormant period, and the above-ground nutrients were gradually transferred to underground rhizomes. At this time, sufficient oxygen was supplied to the soil to promote the growth of winter shoots on the underground rhizomes and stems. Therefore, after harvesting, dry field water should be used to dry the field, and after the fine cracks on the field surface, the water should be rehydrated. Rehydration is carried out before the onset of frost. Generally, the water level is maintained at 2-3 cm. After December, the water level can be deepened to 7-10 cm to protect the underground rhizomes from wintering safely. The weather turned fine in early March and the water level dropped to 2-3 cm.

Scientific fertilization between the cold and the beginning of spring, per acre Shiren familiar manure 4000 kg, in order to ensure the quality of fleshy stems, not stiff. Base fertilizer application can not be later than the beginning of March. After the beginning of spring, when the white seedling height is about 20 cm, combined with cultivating and weeding, apply 25-30 kg of urea or 40-50 kg of ammonium bicarbonate per acre to promote sprouting of new shoots.

The seedlings of the seedlings in the late winter and early spring of the patching seedlings were checked as soon as possible when the seedlings germinated on the old seedlings. Where there are no piers, the new seedlings to be cut and germinated will be made up. Too many germinating seedlings on the old loquat piers should be cleared, and some weak and weak seedlings must be removed.
