This year's new apple crop reduction is already a foregone conclusion, but the price increase will not be too large
With this year's early cold snap in late spring, and the emergence of long-period frosts and hail, the reduction of the new-season apple crop is already confirmed, but specific figures range from 30% to even half; Science Xingnong believes that production will decline somewhat, but...

Causes of the 1999 yield reduction of Jin jujube in Ning County and the solutions
Jin jujube cultivation in Ning County, Gansu Province is concentrated in Zaosheng Town. In 1999, the bearing area was 100 hectares, with a total yield of 212.5 tons, which was 22.3 tons less than the average over the years, a reduction of 12.5%, making it a year with relatively poor yield in history. I. Causes of the Jin jujube yield reduction 1. Severe jujube witches' broom disease: According to a survey conducted in Xinzhuang Village, Zaosheng Town, Ning County, before 1997 the rate of diseased plants of jujube witches' broom accounted for 3.98% of the total number of trees, and all diseased trees were fruit-bearing trees. By 1999, the number of trees with jujube witches' broom had risen to 1387, accounting for 10.05% of the total

What to do about a high egg breakage rate? Sharing effective reduction methods
Broken eggs account for about 6-8% of total egg production, bringing considerable losses to laying hen production. Below are methods to reduce egg breakage. 1. Meet nutritional needs, especially calcium and vitamin D3 levels, while keeping phosphorus at an appropriate level and managing the calcium-to-phosphorus ratio well, generally around 3.4-4.6:1. 2. Increase the frequency of egg collection, avoid eggs colliding with each other, especially during peak laying hours, and handle eggs gently when collecting and moving them. 3. In hot seasons, appropriately increase

Major progress made in project to control soybean yield reduction from continuous and alternating cropping
The reporter learned from relevant departments that the project "Research and Demonstration of Key Technologies for Controlling Soybean Yield Reduction under Continuous and Alternating Cropping," tendered by the Municipal Science and Technology Bureau, has achieved major progress after two years of scientific research. The project was carried out in Yilan and Bayan counties, the two counties with the largest soybean area in Harbin. Through key technology research, soybean varieties resistant to continuous and alternating cropping were selected, including Kenfeng 16, Heinong 48, Kangxian 4, and Hefeng 47. A formula fertilization technique was proposed with 45 kg of nitrogen, 60-67.5 kg of phosphorus, 67.5-75 kg of potassium, and

Reasons for Yield Reduction in Continuous and Alternate Soybean Cropping and Yield-Preserving Techniques
I. Reasons for Yield Reduction in Continuous and Alternate Soybean Cropping Continuous and alternate soybean cropping causes plants to grow slowly and become short, with yellowing leaves, fewer pods, and fewer seeds, ultimately leading to a significant reduction in yield. In the short term, continuous and alternate cropping intensifies the damage from cyst nematodes, root maggots, root rot, pod borers, gray leaf spot, and malignant weeds, causes unbalanced depletion of soil nutrients, leads to deficiencies in soil nutrient elements, increases pathogenic fungi and decreases beneficial bacteria in the soil, and produces certain toxins, resulting in a severe decline in soybean yield and quality. In the long term, after long-term accumulation and reproduction, diseases, insects
