Self-pesticide potatoes successfully cultivated in Belarus
Scientists in Belarus have become the first in the world to cultivate potatoes that can automatically kill pests. A scientist involved in the research said that through experiments they successfully transplanted a special gene into the potato plant, and this gene can continuously produce a toxin lethal to the Colorado potato beetle (the toxin is harmless to humans). Therefore, when the Colorado potato beetle begins to damage the potato stems and leaves, the toxin quickly penetrates the insect's body and poisons it to death.

Why oyster mushroom mycelium fails to fruit for a long time after fully colonizing the substrate, and how to fix it
In oyster mushroom cultivation, you sometimes run into bags or blocks whose mycelium grows very well but, after fully colonizing the substrate, produce no mushrooms for a long time. The main causes and remedies are as follows: 1. The oyster mushroom variety does not match the season. The temperature type of the spawn differs too greatly from the air temperature at cultivation time, which is to say the sowing time was chosen poorly. For example, if a medium-to-low-temperature oyster mushroom spawn is sown at the turn of spring and summer, the mycelium fully colonizes just as the hot season arrives, making fruiting very difficult. Remedy: dig a trench in a shady spot, arrange the bags in it and cover them with soil to oversummer; when the autumn cool arrives and conditions are suitable, dig away the soil cover and carry out fruiting management to reduce losses.

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

Hainan successfully breeds a new high-yield, high-quality glutinous rice variety
The Hainan Academy of Agricultural Sciences has successfully bred a glutinous rice variety, "Haifeng Nuomi No. 1," which has better quality than the traditional Li ethnic group's mountain orchid rice (Shanlan rice). This variety has the advantages of high yield, disease resistance, cold tolerance, lodging resistance and good glutinous quality, with an average yield per mu 4 times that of Shanlan rice. Shanlan rice, also called "Shanlan rice" (mountain-blocked rice), refers to a type of upland glutinous rice planted by the Li people of Hainan, China, who cut out a patch of land on the mountain and enclosed it for cultivation. It is suitable for brewing wine, and Shanlan wine is called the champagne of the Li ethnic group. Therefore, Shanlan rice is the traditional crop most beloved by the Li ethnic group.
