First, in addition to membrane earth
When the stalks and leaves of potato mulching film reached a height of about 30 centimeters in the early spring, the tubers began to swell before and after potato sprouting. When the outside temperature was stable at around 25 degrees Celsius, the mulch film covering the ground should be promptly removed. After removing the mulching film, weeds should be removed from the ridges in time, and soil should be cultivated twice in the potato roots. Earthing can increase potatoes yield and prevent the occurrence of potato tuber scab.
Second, watering and fertilizing
Potato tuber enlargement requires sufficient water and fertilizer supply, and when the tubers have the size of walnuts, it can increase the top dressing fertilizer. Potatoes belong to the Potassium-type crops, and the demand for potash is larger. When watering, 20kg of nitrogen and potassium fertilizers are topped off by the mu, and topdressing once every 10 days, followed by topdressing twice. When encountering continuous dry weather, it is necessary to pay attention to watering in time to prevent soil drought from affecting tuber enlargement.
Third, control pests
When potatoes enter the late growth stage, the main pests are aphids and cockroaches. Locusts suck the sap of potato leaves, and it is also very easy to spread potato virus disease, which obviously affects the yield. Can use 10% imidacloprid 800 times spray control, spray once every 7 days, and even spray 2 times. Cockroaches are a major underground pest that affects potato production. They bite into potato tubers, causing a drop in yield and a deterioration in the quality of goods, affecting planting income. The use of phoxim to irrigate the roots, with a dose of 1 to 1.5 kilograms per mu, combined with water irrigation before and after the evening, can play a significant control effect.
A CT scan makes use of computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of specific areas of a scanned object, allowing the user to see inside the object without cutting.
