Rice direct seeding machine successfully developed, efficient and versatile, boosting rice sowing
Recently, a "Multifunctional Soil-Covering Direct Seeding Machine Rice Mechanical Direct Seeding Field Demonstration" organized by the China National Rice Research Institute was held in Buqiao Village, Fuyang City, Zhejiang Province, with more than 40 experts from home and abroad attending the field observation event. In recent years, China's rice mechanical transplanting technology has developed rapidly, and a number of different types of transplanters suited to China's rice production have been developed and produced. However, the development and research of rice direct seeding machines and mechanical direct seeding technology have lagged relatively behind, and no mainstream rice mechanical direct seeding technology has yet taken shape. To overcome the problems of poor seedling establishment, easy lodging, premature aging, and difficult and costly weed control

What are the characteristics of each developmental stage of soybean?
(1) Germination stage: refers to the period from seed germination to seedling emergence, which takes 10-15 days for spring soybeans and 4-6 days for summer soybeans. The germination stage of soybean mainly requires appropriate temperature and suitable soil moisture. It is required to carry out seed treatment before sowing, improve the quality of land preparation, sow at the right time, ensure that the field soil is loose, and prevent excessive soil moisture and poor permeability, which can delay seedling emergence or even cause seed rot. (2) Seedling stage: refers to the stage from seedling emergence to flower bud differentiation. It requires an average daily temperature above 20°C and 19%-20% soil

Analysis of the Introduction Performance and Development Strategies of Southern Pears in Hezhou
According to the deciduous fruit development concept of "southern pears and northern peaches" proposed by the Ministry of Agriculture in 1996, Hezhou City, Guangxi, began introducing southern pears from Zhejiang University, Guilin, Guangxi, and other places in 2000. A total of 11 southern pear varieties were introduced, and the current cultivation area is 1066.67 hm2. It is expected that the pear output in 2006 will reach 25,000 t. Based on current introduction observations, the soil, climate, and other natural conditions in Hezhou City are very suitable for the growth of southern pears. Many varieties show advantages such as high and stable yield, good taste, rich flavor, and strong resistance. The products are widely welcomed by consumers in the market.

Development and Utilization Value and Methods of Kernel Apricot Flesh
I. Dried Apricot Processing 1. Process flow: apricot flesh → washing → sulfur fumigation → drying → finished product 2. Technical points: (1) Washing. Select flesh that is uniform in appearance, fully ripe, with no fuzz on the fruit surface, small in fruit size and thick in flesh; wash clean with water and drain off the moisture. (2) Sulfur fumigation. Send the material baskets or bamboo trays holding the apricot slices onto the wooden racks in the fumigation room, pour the burning charcoal into the iron pan in the center of the fumigation room, quickly sprinkle sulfur (3-4 kg of sulfur per 1000 kg of apricot slices) onto the charcoal, then leave the fumigation room immediately

What measures promote rice root development?
1. Sow early at the right time. When the temperature stabilizes at 5°C, begin sowing and raising seedlings; do not raise seedlings for the May crop. When the temperature stabilizes at 13°C, begin transplanting; do not transplant for the June crop. Transplant during the high-yield period to gain accumulated temperature, which is beneficial to root development. 2. Prepare the land carefully and create the conditions. Do a good job of plowing and rotary tilling; generally the plowing depth is 20 cm and the rotary tilling depth is 14 cm. Keep the plowing or rotary tilling depth uniform, so that the mud is not exposed even in water an inch deep, creating the conditions for root development. 3. Strengthen management and promote development. First, seedling-field management: control the temperature well, water reasonably, spray fertilizer on the leaves, and prevent

Detailed Explanation of the Development Method and Production Process of Oyster Mushroom Yogurt
Oyster mushroom is an edible fungus that is easy to cultivate, has high yield, and is deeply loved by the general public. Oyster mushroom has tender flesh, a delicious taste, and rich nutrition. Every 100g of dried mushroom contains 23-28g of protein and 1.42-2.87g of fat; the protein contains 18 kinds of amino acids, and the 8 essential amino acids for the human body and 2 semi-essential amino acids (arginine, histidine) account for about 40-50% of the total amino acid content. It also contains trace elements such as phosphorus, potassium, iron, zinc, and copper, as well as rich Vc. Oyster mushroom has very high medicinal value

Garlic Harvester Successfully Developed in Chengwu, Shandong
The garlic planting area in Chengwu County has remained stable at 400,000 mu, and garlic harvesting has always relied on manual digging, which is highly labor-intensive and inefficient. In order to reduce the burden on farmers, engineer Qin Zhongliang of Dachi Group, after years of effort, finally developed a garlic harvester suited to the county's planting characteristics. The product features high harvesting efficiency, good harvesting quality, no damage to the garlic, no rotting of the garlic, no damage to intercropped crops, and easy operation. It can shovel two rows of garlic out from the roots at one time, after which the garlic is picked up by hand. Each person can harvest

Current Status, Existing Problems and Future Development Directions of Sericulture in Guizhou
1 Current Status of Development As a traditional export industry of China, the cocoon and silk industry, since entering the "10th Five-Year Plan" period, has adhered to a market-oriented approach, taken development as its theme, and relied on reform, opening up and scientific and technological progress as its driving forces. By comprehensively applying the state's reform and development policies, strengthening macro-control, and intensifying structural adjustment, it has effectively overcome the phenomenon of "drastic fluctuations," enabling the entire industry to emerge from the trough and basically maintain sustained and steady development. The quality of economic operation has improved markedly, with production capacity, efficiency and export earnings surpassing the best historical years. "Chinese silk

Detailed Explanation of the Growth, Development and Functions of Rice Roots
After the seeds are pre-germinated, they sprout and grow roots. At first, only one root grows, called the seminal root (primary root), which develops from the radicle of the seed. The fibrous roots that later grow from the root primordia at the stem nodes are called adventitious roots. The coleoptile node and the incomplete leaf node produce about 5 roots, the first, second and third leaf nodes produce about 10 roots each, and the nodes above the fourth leaf position produce about 10 to 20 roots each. This is because the leaves increase in size in sequence from bottom to top, so the nutrients supplied for root growth increase in sequence, and the number of roots produced also increases. The nodes of the aboveground part generally do not produce roots. The nutrients produced by the leaves are

Proper drought and disease prevention management during the garlic scape development period
The garlic scape development period is the reproductive growth stage of garlic, mainly including the flower bud differentiation stage and the scape elongation stage. The differentiation of flower buds and bulbils is a critical period in garlic growth and development, and smooth differentiation helps increase yield. The scape elongation stage refers to the period from when the scape begins to elongate until the scape is harvested after the tail-flicking stage, about 30 days. During the garlic scape development period, flower bud differentiation requires temperatures below 10°C; the scape elongation stage requires an optimal temperature of 12°C-18°C. If the temperature is too low, the scape elongates slowly, affecting yield; if the temperature is too high, the scape elongates quickly, the fiber content increases, and quality deteriorates.
