Sweet potato insect control secret inheritance, help you grow sweet potatoes smooth and insect-free, agricultural experience sharing
Preface: I looked at the vigorous sweet potato field next door, and the red sweet potato vines were thriving in the warm afternoon sun. However, when I heard that my aunt was going to give me some sweet potato seedlings, my good mood changed.
Chapter 1: An overview of the underground pests of sweet potatoes.
There are many types of underground pests of sweet potato, among which grubs and mole crickets are the most common and serious pests. They invade sweet potatoes in two ways, one by the natural invasion of adult insects, and the other by manure that is not completely decomposed. Sweet potato is an important agricultural pest in China, which endangers potato production, potato production, human health, and human health.
In order to fundamentally control the pests in the underground of sweet potato, only conventional measures can be adopted. This practice is environmentally friendly and guarantees the quality and taste of sweet potatoes. Due to the use of pesticides, the safety of food is greatly jeopardized, so the best way to do this is to use the traditional way.
Chapter 2: Advantages of traditional control measures in China.
The traditional control method is mainly to protect the environment and control, and has no negative effect on the growth of sweet potato. This is very different from the idea of applying pesticides. Under the premise of controlling pests, the normal growth of sweet potatoes can be ensured in conventional ways. The use of pesticides to control pests can only alleviate the symptoms, while the use of traditional control measures can completely ** pests.
Chapter 3 Methods for handling quicklime.
Quicklime is a simple and practical method to control pests in the underground of sweet potato. Half a month before the sweet potato transplantation, 50-75 kg of quicklime is applied to one hectare of land and then sprinkled on the land where the sweet potato is to be planted. Next, the soil is ploughed with a mouldboard and the quicklime is turned into a sweet potato growing circle under 30 cm. Third, the ploughed land should be properly irrigated so that water can penetrate the quicklime layer. Quicklime reacts chemically when exposed to water, releasing a huge amount of heat energy that can burn eggs and adult insects to death. At the same time, it can also improve the soil pH value, supplement nutrients for the growth and development of sweet potato, improve soil quality, and achieve the purpose of increasing yield.
Chapter 4 Methods for Dealing with Lime Soil.
The present invention provides a simple, effective sweet potato underground pest control technology. When transplanting and sowing sweet potatoes, 100 kg of plant ash is sprinkled on each hectare of land, and then it is spread evenly. Grass ash is rich in nutrients and has a good nourishing effect on sweet potato. At the same time, the plant ash also has a certain killing effect on snails, which can effectively prevent the harm of larvae and grubs. In addition, it also has the effect of regulating soil quality, improving soil quality, improving plant resistance, and making plants thrive.
Chapter 5 Measures to prevent green manure.
Green manure fields are a natural means of controlling pests. Before cultivating sweet potatoes, it is necessary to choose suitable green manure, such as peas, milk vetch, etc. Green manure fields can effectively draw nutrients from the soil and reduce the number of pests. Green manure can also improve soil structure, improve the accumulation of organic matter and the ability to retain water and nutrients. In the process of cultivating sweet potato, the green manure is returned to the field, which improves the organic matter in the soil and is conducive to the growth and development of sweet potato. It can not only effectively control pests, but also increase the yield and quality of sweet potatoes.
Chapter 6: Summary.
In sweet potato production, pests are badly harmed. In order to prevent the occurrence of pests, conventional measures such as quicklime, plant ash, and green manure can be used. This is not only environmentally friendly, but also increases the yield and quality of sweet potatoes. In production, we should pay attention to prevention and comprehensive prevention and control, so as to ensure the healthy growth and abundant yield of sweet potato.
