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

First Aid for Dog Poisoning from Household Products
For puppies that don't understand danger and are full of curiosity, a seemingly safe home can be full of hidden hazards. When leaving a puppy home alone, don't underestimate its ability to rummage through everything. Be sure to properly store away all items that pose a threat to it, such as toxic items, electrified items, things that can't be digested if swallowed, and sharp or heavy objects. The following common household toxic substances require extra vigilance: alkaline detergents: dogs may accidentally knock them over and become poisoned, showing symptoms of skin burns; do not induce vomiting during rescue. Solvents or thinners: owners

Introduction to the Nanshui Pear variety: a pear variety originating from Japan
In Japan in 1973, it was crossed from Echigo and Shinsui, sown and raised as seedlings, selected in 1983, and tested and observed for characteristics as Nannong Pear No. 1, and obtained legal variety registration in June 1990. Late-maturing variety. The fruit is oblate, with an average fruit weight of 360g, and the fruit shape is uniform. The skin is yellow-red, the fruit dots are medium, and the fruit surface is smooth. The flesh is white, the soluble solids content is about 15%, the taste is sweet and sour, and juicy. It matures from mid-September to early October, basically the same as Shinshin. No heart rot, fruit cracking, or water core symptoms

Detailed Guide to the Technical Method for Making Maltose from Potato Residue
Potato residue is the by-product left after starch extraction. Using this residue to make maltose turns waste into treasure. 1. Making malt: Soak barley in clean water for 1-2 hours, keeping the water temperature at 20-25°C. Scoop out the barley and place it indoors at 25°C to germinate, sprinkling water twice a day. After 4 days, once the malt has grown to more than 2 cm, it is ready. 2. Ingredients: Grind the potato residue fine, sift it, add 25% rice husks, sprinkle 8% clean water onto the prepared ingredients, mix well and let stand for 1 hour. Steam the mixture in a steamer in 3 batches,

How is reagent-grade starch made from potatoes?
Using potatoes, reagent-grade starch can be produced with low cost and high economic benefit. Production method 1. Washing and making potato pulp: Wash the potatoes with water 2 to 3 times, remove all mud and sand, and cut away potato pieces with hoe injuries and rotten holes. Start the crusher, feed in the washed potato pieces, and the potato pulp will flow out immediately. Because fresh potatoes themselves contain about 75% water, no additional water is needed when pulping. 2. Filtering the pulp and rinsing the starch: Filter the potato pulp by machine or by hand, and store the starch milk (water containing starch) in a tank to clarify. Wait for the starch in the tank to settle to the bottom

Method for Making River Crab Feed from Potatoes
Using potatoes to make river crab feed has the advantages of widely available raw materials, low cost, good palatability and rich nutrition, and river crabs like to eat it and grow readily. At the same time, this feed-making method is relatively simple; it can be produced on a large scale with machinery or made by hand, so potato crab feed has broad application value. The key processing and feeding techniques are introduced below for the reference of aquaculture farmers. Process flow: material selection -> cleaning -> cutting into pieces -> steaming -> crushing -> ingredient mixing -> shaping -> drying. Processing techniques: (1) Material selection. Choose potatoes free of pests and diseases, without sprouting,

How to prevent potatoes from sprouting during storage? Practical tips shared
To prevent potatoes from sprouting during storage, you can spray the field with maleic hydrazide at a concentration of 2-3 g/kg in the late growth stage (that is, 2 to 3 weeks before harvest); you can also spray the whole plant with 2,4,5-T at a concentration of 0.5-1 g/kg 1 week before harvest to extend the dormancy period and storage period; in the late growth stage, mixed spraying of the whole plant with maleic hydrazide at a concentration of 3 g/kg and 2,4,5-T at a concentration of 0.3 g/kg has a better effect on preventing sprouting. In addition, after the potatoes are harvested,

High economic returns from raising adult crabs as a supplementary crop in fingerling ponds
Raising adult crabs as a supplementary crop in fingerling ponds, relying on high density for success, practicing ecological farming, and replacing concentrated feed with coarse feed, is a new low-input, high-output farming model that the author has summarized from years of practice. Last year, in a pond of two mu, the author invested a total of 1,000 yuan in fingerling costs and feed costs. The result was an output of 70,000 "huopian" fingerlings worth 3,000 yuan, 20,000 one-year-old fingerlings worth 4,000 yuan, and 40 kg of adult crabs worth 1,000 yuan, for a total output value of 8,000 yuan. After deducting costs, the per-mu

How to Save Seeds from Angelica sinensis? Detailed Key Points of Seed-Saving Technique
Select disease-free plants or a field plot; do not dig them up in the autumn of that year. After seedlings emerge the following year, carry out normal field management. 30~40 days after bolting, that is around mid-August, when the seeds turn from red to pinkish-white, harvest the seeds. Because the seeds do not ripen uniformly, they can be harvested in batches. When harvesting, collect the seeds together with the fruit stalks, tie them into small bundles, dry them in a cool place and thresh them, then store them in a ventilated, dry place. Avoid heat and moisture.

Methods for Authenticating Panax Notoginseng: How to Tell Real from Fake
Panax notoginseng, commonly known as Tianqi, is considered best when the roots are large, heavy, smooth on the surface, brown-black, hard in texture, and grayish-green or yellow-green on the cut surface. Among the people, its quality and price are often determined by how many Tianqi rhizome pieces make up each jin: the larger the heads, the better the quality and the higher the price. If 20 Tianqi heads make up 1 jin, this is the best, called the "King of Seven." If 60 to 80 Tianqi heads make up 1 jin, they are called 80-head. If each jin contains more than 300 Tianqi heads, they are called headless grade, the poorest quality. Panax notoginseng tastes slightly bitter when chewed, with no numbing or spicy sensation, and breaks easily. It is easily confused with
