The technique of continuous cropping in cucumber production is very common, and even a long period of time will lead to the occurrence of some cucumber diseases. With the increase of the continuous cropping time, the diseases and insect pests of cucumber have increased year by year. The following bio-fertilizer expert, Jinbao, will combine the symptoms of cucumber as a frequent occurrence for the farmers' friends to provide solutions to several diseases.

1. Cucumber root-knot nematode disease Root-knot nematode disease is caused by the soil not being renewed or organic fertilizer being sufficiently decomposed and causing the eggs to be carried into the soil. The most fundamental solution to such problems is to disinfect the matrix and basal fertilizers on a regular basis. The vegetable farmers can use organic fertilizer to make organic fertilizer to reduce the introduction of exogenous nematodes. Due to the high level of fertilizers decomposed by the golden treasure organic fertilizer, it will effectively kill the eggs of the exogenous nematode and it will not be easy to burn the seedlings. Therefore, it is safer and more reliable than composting for vegetable farmers.
Once the root-knot nematode has occurred, the vegetable farmers can use the characteristics that the nematode can be lethal at 55°C for 5 minutes, and use the methods of summer lime, rice straw, flooding, and mulching. Or use basal fat while adding dichlorvos and zizag milk to kill nematodes in the soil.
The main manifestations of root-knot nematode disease are the grotesque or bead-like root knots on the lateral roots and fibrous roots of the affected plants. The roots are mostly white at the beginning, and light brown or even black at the later stages. Some of them have thin new roots. In severe cases, they form a cluster of fibrous roots, with root knots in the middle, and open root knots, which contain milky white nematodes.
2. Cucumber Phosphorus deficiency Cucumber is a very sensitive crop to phosphorus. Phosphorus is especially needed during seedling period. Phosphate should be added. To prevent acidification of the soil, sufficient organic fertilizers such as compost should be applied. After application of compost, phosphate ions are not directly in contact with the soil, which reduces the chance of being bound by iron and aluminum, and is beneficial to the absorption of phosphorus. In order to increase the absorption of phosphate fertilizers, we can use some biological bacterial fertilizers, such as Golden Baby microbial fertilizers, to promote the absorption of phosphorus and potassium fertilizers. Once the symptoms of phosphorus deficiency appear, we need to take emergency measures: spraying potassium dihydrogen phosphate solution.
Dwarfing but not obvious when cucumber lacks phosphorus. Plant growth is blocked. The leaves are small. The leaves are dark green. The stems are short and fine. The old leaves have obvious dark red patches. The leaves are hard and slightly upward; sometimes the spots are brown. The lower leaves are easy to fall off; the fruits are small, mature late; fibrous roots are not well developed.
3. Anthracnose of cucumber Anthracnose was attacked by the main stems and leaves of the anthracnose, and small spots of water-soaked shape appeared at the beginning. After that, it expanded into round lesions, reddish-brown, and surrounded by a circle of yellow lines. When the wet spot appeared pink sticky material in the center of the lesion, the lesions cracked when it was dry, and the melon strip bent or deformed from the diseased part. Anthracnose control can be controlled by the use of basal fertilizers and the use of related wettable granules such as metalaxyl manganese zinc in the early stages of disease.

Jilin Province, as the main corn producing region in China, is also in the main grain exporting province of the country. It has been the first in China in terms of total corn production and commercial grain rate. There has the mosst excellent soil and climate which are suitaable for corn growth. The corns there have high yield and excellent quality, are ideal raw materials for processing fresh sweet and waxy corn.Corn planting in the Northeast region is mostly one crop a year, and spring sowing is mainly based on clearing, which accounts for more than 50% of the corn planting area in the Northeast.
In addition to clearing, the importance of corn in crop rotation cannot be ignored. Rotate crops with sorghum, millet, soybeans and other crops to improve crop yields.
Affected by climatic characteristics, the choice of corn varieties in Northeast China is to choose varieties with moderate maturity or early maturity, and at the same time have the characteristics of low temperature tolerance and high yield.
