Comprehensive Utilization Techniques for Fish Fingerling Ponds During the Winter Fallow Period
Using Winter-Fallow Fingerling Ponds to Raise Marketable Fish Raising a crop of marketable fish in winter-fallow fingerling ponds can both increase production and help regulate the "summer shortage" in the aquatic product market. Because the rearing period is relatively short and temperatures are low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fingerlings are concentrated in ponds, so as to make full use of the growing period. Based on a maximum water depth of 2 m, the usual stocking rate is 125-150 kg per mu. The usual stocking ratio is about 40% silver carp, about 10% bighead carp, about 30% grass carp and bream, and about 20% black carp and common carp. Stocked fish

Detailed Explanation of the Key Technical Points of Jujube-Grain Intercropping
1 Scientific Basis of Jujube-Grain Intercropping 1.1 Seize the time difference between the growth of jujube trees and intercrops to make full use of fertilizer and water resources. The jujube tree is a fruit tree that sprouts late, sheds its leaves early, and has a relatively short annual growth period. It generally begins to sprout in mid-April and sheds its leaves in mid-to-late October, while wheat is sown in late September and harvested in early June of the following year. The symbiotic period of jujube trees and wheat is about 80 to 90 days. From mid-May to early June is the period when wheat flowers, fills grain, and matures, mainly absorbing phosphorus and potassium fertilizer, with nitrogen fertilizer as a supplement. And the jujube tree is precisely in the period of growing leaves, differentiating young buds

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.

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.

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

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

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

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,

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
