The traditional cultivation method of celery is usually planted from September to December and harvested from December to April. Planting celery in the off-season in May-June sowing, harvest from August to September is better. In the process of planting celery in the off-season, a variety of problems are often encountered. If you need to make a good five, you can make celery more productive.
First, sowing close
Celery can be cultivated in summer and can also be transplanted. Sowing in early May to late June, when the high-temperature and heavy rain season occurs, there is a high demand for varieties, and varieties with heat-resistance and resistance should be selected. Before sowing, the seeds should be soaked, soaked in warm water at 48°C for half an hour, and then germinated until the seeds are 50% germinated. Celery sprouts slowly, seedling period is very long, in order to prevent high temperature and ground temperature injury seedlings, to promote emergence and prevent heavy rain erosion, should be shaded in the surface, the commonly used shade cover are: straw, straw, shade net, etc. Remove the cover after emergence, so as not to affect the growth of celery. The seedling age is controlled at about 40 days, and 5 to 6 leaves can be planted.
Second, set off
Apply per acre rotted farmyard fertilizer 3000 ~ 5000 kg, ternary compound fertilizer 40 ~ 50 kg. Plunge over 20 cm deep to fully mix the soil and fertilizer. 2 to 3 days before transplanting, stop watering, dig seedlings with shovel soil, dig the seedlings as far as possible without damaging the leaves and roots, and allow the plants to bring more soil, which will facilitate survival after planting. The celery seedlings are planted according to the size and size of the seedlings. Colonization should be carried out after 5 pm and the root water should be set after planting.
Third, the shade off
Summer cultivation of celery should cover shade nets to cool and moisturize, which is beneficial to growth, reduce fiber, and improve quality. After planting, use shade nets to form a shed or flat shed. The height of the shed is 2 to 2.5 meters. It is better not to use celery when it is exposed to sunlight from 10 am to 3 pm. Summer celery should be shaded throughout the growing season. Covering the shade net can reduce the light intensity, reduce the evaporation of soil moisture, help moisture and drought, and reduce the mechanical damage caused by heavy rain on celery.
Third, Tian Guan Guan
The early growth of celery is slow, but it is also a high-temperature rainy season. It is often a harm to weeds. Therefore, we should cultivate the weeds in time. It is common to combine tillage and weeding before every top dressing. Since the root system of celery is shallow, the cultivator should be shallow, as long as it can achieve the purposes of weeding and loosing, and it must not be too deep to avoid damaging the root system. The growth period of summer celery is short, so the application of nitrogen fertilizer is mainly to promote the growth of stems and leaves. Fertilizer applied on the basis of fertilizing basal fertiliser, after the emergence of 5 to 7 days, the first topdressing urea 10 kg/mu, after every 8 to 10 days a topdressing, Mushi urea 10 to 12 kg, generally need to top dressing 4 times. During the growth period of summer celery, spray 2 to 3 times of soluble boron or superphosphate leaching solution to prevent cracking and rotten heart petiole, and prevent yellowing of the petiole in the later period. The growth and development of Xia celery requires moist environmental conditions. From the start of sowing to the harvest of celery, we must ensure that the field is moist for the growth of stems and leaves.
Fourth, pests and diseases
The common diseases of celery include damping-off, blight, soft rot, leaf spot, and anthracnose. Pests include aphids, hummocks, cockroaches, and spotted lilies. Vegetable farmers should pay attention to timely spraying and prevention.
V. Harvest
According to the growth of celery and market demand timely harvest. Due to hot summer celery growing season, is not conducive to the growth of celery, therefore, the harvest is generally earlier than the autumn celery, when the stem is 40 to 60 cm high, good quality, high yield, green leaves and stems, this time harvesting and selling high prices. Take care to prevent injury during harvest and keep the whole plant intact.

Kidney disease refers to various diseases of the kidneys.
Chronic kidney disease (CKD) is defined as chronic renal structural and functional impairment due to various causes (a history of kidney damage greater than 3 months), including normal and abnormal pathological impairment of renal GFR, abnormal blood or urine composition, and imaging abnormalities, or unexplained decline in GFR (< 60ml/min · 1.73m2) more than 3 months, namely, CKD.
Chronic kidney diseases include various primary and secondary glomerulonephritis, renal tubular injury and renal vascular lesions. According to the GFR chronic kidney disease can be divided into 5 phase, early detection and early intervention can significantly reduce the complications in patients with chronic kidney disease (CKD), significantly improve the survival rate, for the treatment of chronic kidney disease (CKD), including the treatment of primary disease, processing a variety of risk factors, and delay the progress of chronic renal insufficiency, when advances for patients with chronic kidney disease (CKD) to 5), should be timely for renal replacement therapy.
