Key recent management focus for zucchini: controlling excessive vigor
Recently, when visiting the countryside, I saw that the zucchini grown in greenhouses by vegetable farmers was generally growing too vigorously, and the plants were setting fruit poorly. When asked why, many vegetable farmers told the reporter: "The weather forecast earlier said this year would be a cold winter, so we thought temperature control alone would be enough to manage plant growth well and avoid excessive vegetative growth. If we also used plant growth regulators, it would very likely seriously affect the growth of the zucchini, so we did not use regulators. But unexpectedly, although the outdoor temperature this year was not high, the weather was clear and fine, and the temperature inside the greenhouse was relatively high, which caused severe excessive growth of the zucchini."

Properly controlling excessive vine growth in sweet potatoes can promote high yields
Sweet potato is a crop with high and stable yields. It has the characteristics of wide adaptability, strong stress resistance, drought and barren tolerance, and relatively few pests and diseases. When planted in places with good water and fertilizer conditions, it can generally yield 2000--3000 kg per mu. However, due to differences in natural conditions and cultivation levels, the yield per unit area is also extremely uneven. In order to fully...

Technical key points for controlling the two-spotted field noctuid moth (Athetis lepigone) during the seedling stage of summer corn
The two-spotted field noctuid moth is a newly emerged pest in summer corn production areas in China. Returning wheat straw to the field provides an excellent environment for the two-spotted field noctuid moth to choose hidden, moist places for laying eggs and hatching. Once the larval peak period coincides with the corn seedling stage and suitable rainfall occurs, it may cause serious damage. The two-spotted field noctuid moth's...

Spring management of wheat: focus on preventing and controlling the four major harms
How to manage the first spring irrigation and fertilization of wheat? The first spring irrigation and spring fertilization have a great impact on wheat yield. For example: if the wheat is too dense, too sparse, or lodging occurs in the later growth stage, it indicates that the timing of the first spring fertilization and irrigation was problematic. Another example: if the wheat stays green and ripens late, and the grains are shriveled and thin, that indicates your spring water and fertilizer use...

What are the key technical points for controlling rice false smut?
Rice is susceptible to infection during the heading and flowering stage, and the pathogen damages some grains on the panicle. At first, a pale yellow-green mass appears at the seam of the glumes, gradually expands, and finally covers the entire glume shell. It is 3-4 times larger than a healthy grain, dark green, with a smooth surface, and later splits open, releasing dark green powder. Weather is closely related to the occurrence of rice false smut;...

Key Technical Points for Controlling Diseases, Pests and Weeds in the Field After Rice Seedling Broadcasting
Southern rice black-streaked dwarf disease is a viral disease mainly transmitted by the white-backed planthopper. It mainly harms staple grain crops such as rice and corn. Once a crop is infected, the plant becomes stunted, tillering increases, and in the later growth stage the diseased rice cannot head or set grain, sometimes resulting in a complete loss of harvest, seriously threatening the safety of our county's grain production. In order to scientifically...

What Fungicide Works Best for Controlling Chinese Cabbage Root Rot
Causes of the Disease: Chinese cabbage downy mildew is a fungal disease that mainly affects the leaves, though the stems and flowers can also be affected. After infection, water-soaked chlorotic spots appear on the upper surface of the leaves, later turning yellowish-brown. As the lesions expand, they are often restricted by the leaf veins and become angular in shape. When the weather is humid, a sparse white mold layer forms on the underside of the leaves, and the disease...
