Management Methods and Technical Key Points for Growing Chinese Toon in a Greenhouse
Chinese toon (Toona sinensis) is a woody vegetable, and its tender leaves are edible. Only when the average temperature over a ten-day period reaches 15°C do the young buds begin to sprout and unfold new leaves. Therefore, open-field Chinese toon in the central part of our province has a harvest period in mid-April. Greenhouse production of Chinese toon involves moving the stems of 1- to 2-year-old Chinese toon that have already dropped their leaves into

Methods and Technical Key Points for Top Grafting and Variety Conversion of Walnut Trees
Among the walnuts currently cultivated on a large scale, seedling trees are in the majority. These seedling trees have mixed populations, severe varietal degeneration, low yields, and poor quality. By adopting the top grafting and variety conversion method, early-bearing walnut varieties bear fruit 1-2 years after top grafting, and late-bearing varieties bear fruit 2-3 years after top grafting, which can significantly improve

Detailed Methods for the Prevention and Control of Slime Mold Disease in Bamboo Fungus
Once bamboo fungus (Phallus indusiatus) is attacked by slime mold, the losses are extremely severe, and mushroom growers everywhere should pay attention to this. This article provides a brief introduction to the damage symptoms, causes of the disease, and prevention and control measures. 1. Pathogen: The pathogen of bamboo fungus slime mold disease is Comatricha pulchella (C. Bab) Rost, also known as the beautiful hair net. Its form consists of sporangia growing in groups, sometimes densely packed, stalked, oval to cylindrical, slightly pointed at the top, dark brown or rusty colored, with a total height of 0.7-1.5mm; the stalk is black, generally shorter than the sporangium, rarely reaching half of the total height; the cyst base membrane is thin and membranous, disc-shaped and solitary, or a group forming a continuous sheet; the columella is straight, gradually tapering upward, nearly reaching the top of the sporangium; the capillitium is dense, curved, dark brown, with main branches relatively thick, branches gradually thinning, with many connections, few free ends, spores spherical, brown when in masses, with a diameter of 6.5-8cm.

High-yield cultivation method for sweet potato by cutting into pieces and direct sowing
In the cultivation of sweet potato by cutting into pieces and direct sowing, planting is carried out 20-30 days earlier than traditional planting. Because the growth period is extended, the yield of fresh sweet potato is generally increased by about 1000 kg per mu. It is a comprehensive high-yield cultivation technique with low investment, large returns, and savings in labor and time. 1. Prepare the soil early. In winter ⟦4 <p>In the cultivation of sweet potato by cutting into pieces and direct sowing, planting is carried out 20-30 days earlier than traditional planting. Because the growth period is extended, the yield of fresh sweet potato is generally increased by about 1000 kg per mu. It is a comprehensive high-yield cultivation technique with low investment, large returns, and savings in labor and time. </p><p></p><p>1. Prepare the soil early. In winter or early spring, open furrows and deep-plow 30 cm, which can increase soil temperature and water content, and use the low temperatures of winter and spring to kill overwintering underground pests and diseases. Form ridges along north-south rows or according to the terrain, with a ridge spacing of 60 cm and a ridge height of 20 cm. The ridge shape should be tall and plump, and the furrow should be deep and narrow, which is beneficial both for drainage and drought prevention and for root tuber expansion. When forming ridges, keep the ridge soil loose, and rake the ridge surface flat and firm. Apply sufficient base fertilizer: per mu, apply 4000-6000 kg of organic fertilizer, 50 kg of ammonium bicarbonate, 50 kg of superphosphate, 20 kg of potassium sulfate, or 100 kg of plant ash. </p><p>2. Carefully select seed potatoes. Choose excellent varieties suitable for local planting. The potato pieces should be uniform in size, and pieces of 100-150 g are better. Remove potato pieces damaged by freezing or pests and diseases. Generally, 50 kg of seed is used per mu. </p><p>3. Cut into pieces and soak the seed. According to the characteristic that the upper end of the potato piece has dense buds and the lower end has sparse buds, the upper part of the potato piece should be cut smaller and the lower part larger. Generally, each piece retains 2-3 bud eyes. Put the cut seed potatoes promptly into a 500-600 times carbendazim solution and soak for 10-20 minutes. The solution temperature should preferably be 5°C higher than the air temperature at the time. Remove, dry, and plant immediately. </p><p>4. Sow in time. The time for cutting into pieces and direct sowing is 1 month earlier than the time for transplanting seedlings. After the seed potatoes come out of the cellar, they should be handled promptly and sown into the field as soon as possible to avoid freezing damage. Before sowing, open a furrow 15 cm wide and 5-6 cm deep on the back of the ridge. After watering the furrow sufficiently and letting the water seep down, place the mother pieces in the furrow with the bud-eye side facing south and up, with a plant spacing of 25-30 cm. After planting, immediately cover with film to help preserve moisture and raise temperature, and promote sprouting. </p><p>5. Strengthen management. In the early stage, replant seedlings in time. When seedlings are about 2 cm high, promptly make holes in the film manually at the emergence points to avoid scorching the young seedlings. At the end of May and the beginning of June, when the soil temperature rises, remove the film in time. In the middle and late stages, pay attention to drainage and waterlogging prevention, protect stems and leaves, and do not turn the vines. Topdressing should not be excessive; foliar topdressing can be carried out. Spray 50 kg per mu of 1% urea or 0.5% potassium dihydrogen phosphate solution on the leaves. At the same time, pay attention to weeding and pest control.</p>
