Management Techniques for Bitter Melon at Each Stage of Greenhouse Cultivation
Bitter melon, also known as bitter gourd, is a plant in the Cucurbitaceae family, an annual climbing herb, edible and of high value, with fruits containing charantin. Growing environment of bitter melon. Temperature. Temperature control: bitter melon prefers warmth, is fairly heat-tolerant and not cold-tolerant. Seed germination is suited to 30-35°C; below 20°C germination is slow, and below 13°C germination is difficult. At around 25°C, seedlings with 4-5 true leaves can be raised in about 15 days, whereas at around 15°C it takes 20-30 days. At 10-15°C bitter melon plants grow slowly, and below 10°C growth is poor; when the temperature is below 5°C, plants suffer markedly. However, slightly lower temperatures and short-day conditions advance the node at which the first female flower appears. The flowering and fruiting period is suited to above 20°C, with around 25°C being optimal. Within the range of 15-30°C, the higher the temperature, the more favorable it is for bitter melon growth and development —— earlier fruiting, higher yield and better quality. Above 30°C and below 15°C are both unfavorable for bitter melon growth and fruiting.

Comprehensive Management Techniques for Chinese Cabbage at the Rosette Stage
Chinese cabbage, a biennial herb, 40-60 cm tall, usually hairless throughout the plant, sometimes with a few bristles on the midrib of the lower leaf surface. Native to northern China, it is a leafy vegetable of the genus Brassica in the family Brassicaceae, usually referring to napa cabbage; it also includes bok choy and the headed cabbage (Brassica oleracea var. capitata) derived from cultivated varieties of cabbage, namely "round cabbage" or "foreign cabbage." Introduced to the south, it is cultivated throughout both northern and southern regions. It was introduced to Japan, Europe and the United States in the 19th century. There are many types of Chinese cabbage; northern napa cabbage varieties include Shandong Jiaozhou napa cabbage, Beijing green-white, Tianjin hemp-leaf napa cabbage, Northeast large dwarf cabbage, Yutian napa cabbage, Shanxi Yangcheng large hairy-edge, and others. Chinese cabbage is eaten for its tender leaf heads, rosette leaves or flower stalks. Its cultivation area and consumption rank first among all vegetables in China. <p>Chinese cabbage, a biennial herb, 40-60 cm tall, usually hairless throughout the plant, sometimes with a few bristles on the midrib of the lower leaf surface.

Its cultivation area and consumption rank first among all vegetables in China.</p><p></p><p>Cultivation seasons for Chinese cabbage</p><p>Early-maturing varieties are generally sown in early to mid-August, with some sown as early as late July. Mid-maturing varieties can be sown from late August to early September. Late-maturing varieties are best sown in late August.</p><p>Management of Chinese cabbage at the rosette stage is very important for its production and must be taken seriously, so how should comprehensive management be carried out at the rosette stage?</p><p>The rosette stage is a critical period for napa cabbage growth; at this time growth is rapid and both roots and leaves grow vigorously, but it is also a critical period for disease occurrence. In management, it is necessary to promote rapid leaf growth to form the largest possible leaf assimilation area as quickly as possible, promote rapid root development, control excessive late-stage leaf growth, and prevent disease occurrence.</p><p>Fertilizer and water management. During the rosette stage of napa cabbage, growth speed and growth amount are both very rapid, and fertilizer demand increases. At the early rosette stage, a “plant-development” fertilizer should be applied as a top dressing, with 8-10 kg of urea per mu, by opening a 10 cm furrow on one side of the ridge, applying the fertilizer, closing the furrow and watering; when opening the furrow, take care to damage the roots as little as possible. The heading stage has a high water demand, so full irrigation should be combined with top dressing, generally once every 7 days, keeping the ground constantly moist. Stop watering 10 days before harvest, generally once every 7 days, keeping the ground constantly moist. Stop watering 10 days before harvest.</p><p>Seedling hardening to promote roots. During the period from the mid-rosette stage to the heading stage, napa cabbage is subjected to controlled watering for seedling hardening, controlling excessive growth, thickening the leaves, promoting root development, helping nutrient accumulation, reducing field humidity, and controlling the occurrence and development of diseases. The seedling hardening period varies from 10-20 days, with leaf color changing from green to yellow or slight wilting at noon. In the following situations, reduce seedling hardening: varieties with a short growth period and rapid growth, those sown too late, those transplanted as large seedlings, those with poor seedling condition, dry areas with little rain and higher temperatures, and sandy land short of water and fertilizer.</p><p>Pest and disease control. The main diseases of napa cabbage at the rosette stage are downy mildew and soft rot. Control methods: first, control humidity to prevent downy mildew and soft rot. Second, when disease is found, apply pesticide at the right time to control disease development.</p>
