Shiitake waste can be used to produce straw-rotting mushrooms
For more than a decade, the open-field shiitake industry in Xinbin County has developed on a relatively large scale, and the cultivation materials have shown a growth trend. For a long time, the waste material left after fruiting in open-field shiitake cultivation was always returned directly to the fields to improve the soil, and the issue of utilizing the waste material was never studied. In recent years, due to climatic reasons, the open-field shiitake cultivation model has gradually shifted to the cold-frame connected mushroom-column model, and therefore a great many spent mushroom sticks appear every year. This year alone, cold-frame shiitake was developed on 1,560 frames, and after fruiting there will be 7 million kg of spent mushroom sticks. In these waste materials there are still

Strawflower is both a flower and a tea, good for ornamental viewing and for brewing tea
Strawflower is also known as shell flower. The flowers are hard, shaped like shells or wheat straw, and resemble chrysanthemums, hence the name. The flowers can be brewed as tea and have effects such as cooling and relieving summer heat, refreshing the mind and lowering blood pressure, with no toxic side effects, making them a fine beverage. The flower colors are gorgeous, the flowering period is long, planting is simple, management is extensive, and adaptability is strong. It can be grown in pots or in the ground, and it is very popular. 1. Plant characteristics. Asteraceae, annual herbaceous flower. Plant height 50-70 cm, leaves dark green, long elliptical, lanceolate, leaves alternate, 7 cm long and 2 cm wide. Flowers double-petaled, flowers stra

Straw can be processed into silage. How is it done?
Processing fresh straw into silage that livestock relish is simple, quick and labor-saving. The specific method is: on a harvested rice field or a threshing floor, lay out an extra-large nylon film bag with a thickness of 0.15 cm; then fill the bag with fresh straw, forming it into a haystack shape; finally, tie the bag opening tightly so that no air can enter. After about 1 month, the fresh straw has finished fermenting in the sealed plastic bag and becomes a feed with good palatability, which can replace other silage to feed livestock.

Key Technical Points for Autumn Potato Cultivation with Rice Straw Mulching (Part 2)
4. Timely early sowing. Potatoes prefer a cool climate, and the sowing period should be when the daily average temperature steadily drops below 25°C. In plain and hilly areas below 500 m in altitude, the suitable sowing period is from late August to early September; in low mountainous areas at 500-800 m in altitude, the suitable sowing period is in late August. 5. Reasonable close planting and sufficient base fertilizer. For fields with rice stubble potatoes intercropped with rapeseed, both potatoes and rapeseed are planted in wide-narrow row patterns. For potatoes, the wide row is 0.6 m, the narrow row is 0.2 m, the hill spacing is 0.22 m, and about 700

Key Points of Straw Mulch Cultivation Techniques for Autumn Potatoes (Part 1)
The straw mulch cultivation technique for autumn potatoes is a new technique used in the stubble field after mid-season rice harvest, adopting no-till surface sowing with straw mulching after sowing to cultivate potatoes. It saves labor, effort and time, provides heat preservation, moisture retention, waterlogging prevention and weed control, returns straw to the field to build soil fertility, increases soil organic matter, improves soil structure, reduces soil erosion, improves the agricultural ecological environment, and promotes sustainable agricultural development. It is an important technique that saves labor and costs, increases yield and efficiency, and optimizes the structure of late-autumn grain and oil production. Its key cultivation techniques are as follows:

Key High-Yield Techniques for Cultivating Oyster Mushrooms on Rice Straw
High-Yield Techniques for Cultivating Oyster Mushrooms on Rice Straw 1. Selecting spawn: Experiments show that the relatively ideal strains include: the low-temperature type 792 and 118 oyster mushrooms; the medium-temperature type Xinnong No. 1, 9400 oyster mushroom, and Hypsizygus marmoreus; the high-temperature type Hainan No. 2, etc. (All of these spawns can be provided by the Binhai County Edible Fungi Research Institute.) 2. Seasonal scheduling: Along the middle and lower reaches of the Yangtze River, sowing can be done from early August to mid-February of the following year, with mid-September to mid-November being the best sowing period. 3. Rice straw selection: Choose fully dried, mold-free, golden-colored rice straw

Technical method for three-dimensional cultivation of edible fungi using pure crop straw
For a long time, the culture medium for edible fungus production in China has been mainly wood chips and cottonseed hulls. Excessive logging of timber has caused a shortage of forest resources; and cottonseed hulls, because of their wide range of uses and large consumption, have remained high in price. As a result, the prices of raw materials used for cultivating edible fungi have risen substantially, increasing costs. In this way, those who manage poorly often end up with poor returns, or even losses. In response to this situation, the vast number of edible fungus workers in China, after years of exploration, finally chose to use crop straw for edible fungus cultivation. At that time, the methods used were

Key Technical Points for Winter Potato Cultivation with No-Till or Minimum-Till Rice Straw Mulching
I. No-till or minimum-till field preparation. 1. Selection of no-till or minimum-till fields. No-till or minimum-till potato cultivation is best carried out in sandy loam fields with convenient drainage and irrigation, loose soil, a pH value of 5.5-6, and good water and fertilizer retention. It is especially suitable for planting in sandy loam paddy fields with good drainage and irrigation conditions during the winter fallow period in our city. Fields prone to drought and water shortage and shallow, poor fields, heavy clay fields, low-lying fields, mountain pit fields, cold waterlogged fields, and rotten

Detailed Explanation of Potato Cultivation Technology with Rice Straw Mulching
In 2000, Zhejiang Province carried out research on a new technique for no-till rice paddy cultivation of potatoes with full rice straw mulching, changing "planting seed potatoes" to "placing seed potatoes" and "digging potatoes" to "picking potatoes." The whole process can be vividly summarized as "place, cover, pick," eliminating many operations such as plowing and land preparation, digging holes for planting, intertillage weeding, and digging potatoes. The fresh potato yield per 667 sq m was over 1500 kg. A few years ago, our province introduced this technique and demonstrated it successfully. 1. Select good varieties. Varieties suitable for planting in our province include:

Detailed Explanation of No-Till Potato Cultivation with Rice Straw Mulching
First, selecting the field and preparing the beds. Choose a neutral or slightly acidic paddy field. When harvesting rice, it is best to leave stubble 15-20 cm high. Before sowing, first mark out beds and open furrows, with a bed width of 1.4-1.6 m, a furrow width of 20-30 cm, and a furrow depth of 15-20 cm. When opening the furrows, scatter the excavated soil evenly in the middle of the bed, and shape the bed surface into an arched back to facilitate drainage. Second, seed potato treatment. Select virus-free seed potatoes that are free of pests and diseases, have smooth and fresh skin, and weigh more than 20 g each. Before sowing, according to the distribution of the buds and the
