Key points of high-yield cultivation techniques for rice intercropping of hybrid rice and glutinous rice
Rice "hybrid-glutinous intercropping" refers to the intercropping cultivation of hybrid rice and glutinous rice. That is, medium-stalk hybrid rice and tall-stalk glutinous rice, using the advantage of the wide rows in the wide-narrow row strip planting of hybrid rice, and adding a single row of glutinous rice according to a certain belt width, row ratio and width. 1. Main advantages of hybrid-glutinous intercropping technology. 1. Increasing rice yield: Test results show that the combined total of the two crops under hybrid-glutinous intercropping increases yield by 28 kg per 667 sq m compared with ordinary hybrid rice, and by 110 kg compared with conventionally pure-planted glutinous rice. 2. Increasing income: Glutinous rice is

What to pay attention to when stocking fish fry in reservoirs in winter
Every winter is the golden season for stocking fish species such as silver carp, bighead carp, grass carp, and black carp into reservoirs. But quite a few fish farmers report that within 2 to 7 days after stocking the fry, large numbers of dead fish and swimming sick fish appear on the surface of the reservoir water; these fish lose their luster and their body surface mucus increases. Based on the above symptoms, it can be inferred that the fish have contracted a typical case of "acclimation sickness." This disease is mainly caused by a drastic change in water temperature, in which the nerve endings in the fish skin are strongly stimulated, causing dysfunction of the internal organs, and its death

Key Techniques for Intercropping Sweet Potato with Sesame
Sweet potato is a vining crop with a low light-receiving position. When intercropped with sesame, which has a high light-receiving position, it forms a well-layered crop community, thereby improving light energy utilization. Generally, without reducing sweet potato yield, it increases sesame seed income by 30-40 kg per mu. This planting method is suitable for all sesame-producing regions. 1. Planting methods (1) Sweet potato is cultivated with plastic film mulching. When preparing the land, form ridges with a height of 10-12 cm, a top width of 60 cm, a bottom width of 80 cm, and a ridge spacing of 40 cm. Sweet potato seedlings are raised 7-10 days earlier than usual according to conventional practice.

Why interplanting dry Pinellia ternata in fruit orchards is highly profitable
Dry Pinellia ternata is best suited for interplanting in fruit orchards, because it prefers shaded environments. During hot seasons with direct sunlight, the plants are prone to lodging (seedlings turn yellow, wither and shrink), causing tuber growth to stop. In the hot summer, the lush foliage of fruit orchards serves as a natural protective umbrella that provides shade during the vigorous growth period of dry Pinellia ternata, offering favorable conditions for normal tuber growth. Interplanting dry Pinellia ternata in each mu of fruit orchard can yield about 120 kg of dried product, and its cultivation benefit increases by 3-5 times compared with interplanting conventional crops. 1. Sowing. Spring March-May

Four key points to grasp in winter management of Pinellia ternata
1. Check the seed tubers: Normally, the tubers of Pinellia ternata begin to take root and sprout about half a month after planting. Sometimes, due to low temperatures, tuber rot may occur, so the growth of the seed tubers should be checked in a timely manner. For spots where sprouts have still not emerged, the soil can be gently scraped open by hand or with a bamboo strip, wooden stick, etc. Any seed tubers that have not rooted or whose rootlets are yellow-black are inferior and should be dug out and replanted in a timely manner. 2. Prevent waterlogging and drought: If continuous overcast and rainy weather occurs in winter, the soil is prone to waterlogging and oxygen deficiency, which is not only unfavorable for the tubers of Pinellia ternata to take root underground, but also causes disease and rot. Therefore,

Key Technical Points for Intercropping Pinellia ternata in Woodland
Pinellia ternata, also known as three-leaf pinellia or ground-plant pinellia, is a perennial herbaceous plant with persistent roots in the Araceae family. Its tubers are used as medicine and have the functions of drying dampness and resolving phlegm, and descending adverse qi to stop vomiting. It is shade-tolerant, cold-tolerant, and afraid of sunlight; the seedlings fear heat, so it is suitable for intercropping with trees. 1 Propagation techniques Pinellia ternata is generally propagated by underground corms and bulbils, and can also be propagated by seeds. 1.1 Corm propagation When harvesting corms around Cold Dew, select the smaller ones for seed, bury them in moist soil in a cool, ventilated place, and around Qingming of the second year, transplant them into the field at a row spacing of 10 cm x 6 cm. Transplanting depth

What are the benefits of intercropping cotton with Pinellia ternata?
Through our trials, intercropping Pinellia ternata in cotton fields shows no "conflict" between the two, neither crop's yield decreases, and an additional 80-100 kg of dried Pinellia ternata medicinal material can be harvested per mu, increasing income. The benefits of intercropping Pinellia ternata in cotton fields are mainly shown in the following aspects: 1. Clever use of the time difference. According to the characteristics of Pinellia ternata, it grows well from March to June without shade, and from July to September Pinellia ternata must grow under shaded conditions, and at this time cotton enters a rapid growth stage with luxuriant branches and leaves, creating a good microclimate for the normal growth of Pinellia ternata

High returns from intercropping mushroom cultivation in citrus orchards
The author succeeded in growing mushrooms between the rows of a densely-canopied citrus orchard, achieving a double harvest of both citrus and mushrooms. Large-scale promotion has shown that generally each mu of orchard produces more than 3000 kg of citrus per year, worth 4000 yuan; and 800 kg of fresh mushrooms, worth 3200 yuan. After deducting production costs of 1500 yuan, the total net income is more than 5700 yuan, which is more than 2000 yuan higher than growing citrus alone. Intercropping mushrooms in the orchard also helps to increase humidity, retain warmth and improve the soil. 1 Raw material preparation Each mu requires 1500 kg of dry wheat straw (rice straw or sawdust may also be used), 20 kg of lime and 15 kg of urea

How to intercrop mushrooms and ginger year-round in a citrus orchard
Trees such as mandarin oranges and pomelos are tall and large, and the orchard is generally fairly open yet shaded. To increase orchard income, the author conducted a year-round intercropping trial of mushrooms and ginger in a pomelo orchard about 30 years old with a spacing of 5 m × 5 m. Starting in the autumn of 1989 (September), white mushrooms were planted between the rows, with a planting area of about 44 sq m. By calculation, the investment was about 400 yuan, and the net income from the autumn mushrooms and spring mushrooms reached more than 500 yuan. After the spring mushrooms were harvested in April 1990, the mushroom substrate was turned and buried into the soil, in preparation for planting ginger.

Key Technical Points for Autumn and Winter Management of Pear Orchards
Autumn and winter is an important period when pear trees shed their leaves and enter dormancy. Strengthening the management of pear orchards in autumn and winter is beneficial to the growth, flowering and fruiting of pear trees the following year. 1. Rational fertilization: By the end of November, apply a deep autumn fertilizer to the pear orchard once, and the amount applied should account for more than 30% of the total annual fertilizer application, mainly organic fertilizers such as decomposed oil cake fertilizer, residue fertilizer, composted manure and human and livestock manure. The method is: at the drip line of the canopy of adult pear trees, dig 1-2 ring-shaped fertilization pits about 60 cm long and 25 cm deep and 25 cm wide, and apply 30-40 kg of decomposed human, livestock and poultry manure water fertilizer per tree.
