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 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

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.

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

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

Mock Strawberry
Mock strawberry, also known as ground bayberry, belongs to the genus Duchesnea in the rose family (Rosaceae) and is a perennial low-growing herb. The whole plant is covered with white hairs, and the stems are slender, creeping, and root at every node. The leaves are alternate and palmately compound. The flowers are yellow and borne on long stalks. The fruit is bright red, with a raised central portion that is soft like a sponge. The whole plant is collected in summer and autumn and dried in the sun. A decoction of the whole plant, 15-50 g, taken as a water decoction, can treat cancer.

The role and application methods of wheat straw and wheat chaff mulching
Wheat straw and wheat chaff mulching is the even scattering of wheat straw or wheat chaff around autumn crops or between rows to form a certain mulch layer, with an appropriate amount of soil pressed over it in spots so as to cover and preserve soil moisture. For wheat straw and wheat chaff mulching, it is necessary to properly grasp the principles of timing, mulching amount, and rational application of chemical fertilizers, etc. 1. Timing. The relatively suitable mulching time is from late June to early and mid-July. Too early makes it easy to press down the seedlings, while too late means the crop plants are tall and not easy to work with. After mulching, if there is no rain or the rainfall is insufficient, it will affect the rotting and decomposition of the straw, and the effect will be poor, so timely watering is needed. It is also possible to water at the first topdressing at the end of June.

Key Technical Points for No-Till Planting with Rice Straw Return
No-till technology with rice straw return refers to a simple planting method in which, after the rice harvest, the rice straw is spread evenly over the field, no plowing is done, and only chemical weed control is carried out before wheat can be sown. This technology was successfully developed in May 2000 through dedicated experimental research by the Chengdu Second Institute of Agricultural Sciences. The no-till wheat planting technology with rice straw return fully combines the advantages of straw return, no-till, and broadcasting, and scientifically assembles them into a complete new technology package, which has not yet been formally reported at home or abroad. Experimental research shows that this comprehensive supporting technology not only increases
