Pumpkin stalk can increase production

In the late stage of pumpkin growth, after 2-3 batches of melons, when some waxy yellow leaves appear near the roots, the buried stems are conducive to multi-growing melons and knotting large melons. Premature burying of the stem will cause long, and the late roots will grow slowly.

Pumpkins are generally buried 3-4 knots, combined with vines, appropriate retraction of the main stem part, to ensure that there is enough buried stem length, can not force the stem, should be lightly moved stems.

It is advisable to use a fertile vegetable garden soil to bury the stems, and mix a small amount of organic fertilizer and quick-acting fertilizer. Buried soil should be moist, but too wet will cause rotten roots, too dry is not conducive to adventitious root growth. Buried stem nodes with leaves should be cut off at 1-2 cm from the node, and the buried soil thickness of the node is 15-25 cm. The non-node buried soil should be pressed to effectively prevent disease and decay.

Pheromone

Pheromone is a collective name for compounds that play a role in chemical communication between organisms, and which is the chemical molecular language of insect communication. Including sex pheromone, collection pheromone, alert pheromone, tracking pheromone, altruin, altruin, synergistic pheromone, evacuation pheromone. Pheromones are chemical substances that interact with each other and can affect each other's behavior, habits, and even development and physiological activities. Pheromone is produced by the glands in the body and is directly discharged to the outside. The pheromone is transmitted to other individuals by means of air, water and other conductive media. Pheromones are found in lower animals and higher mammals. Because the pheromone is transmitted by the external environment, it is also called pheromone. Chemical substances that interact between different species are called interspecies pheromones or heteropheres.

Insect pheromones are compounds used by insects to represent various information such as aggregation, foraging, mating, and alerting. They are the chemical molecular language of insect communication. At present, the basic control measures for pests in agricultural production mainly rely on chemical pesticides, but the long-term uncontrolled use of chemical pesticides has brought many side effects. The first is the emergence of pest resistance, which causes the use of drugs and drug concentrations to increase, the cost increases year by year, and the prevention and control of increasingly difficult; the second is to disrupt the ecological balance, while controlling a large number of natural enemies were killed, causing the pupae of secondary pests; Third, it pollutes the environment. A large amount of pesticides remain in crops, soils, rivers, lakes, and seas, and they are enriched in the human body through the form of food chain, causing another harm to humanity. Therefore, relevant research departments in many countries are currently working hard to explore and study new approaches and technologies for pest control. These studies include: the development of new, efficient, environmentally friendly, low-toxic, low-residue chemical pesticides; natural enemy insects and microorganisms The use of pesticides; insect sterilization technology and the application of insect hormones; among them, the research on the use of insect hormones, especially insect sex pheromones for pest control, is receiving increasing attention and attention.

Research on insect pheromone has been developing rapidly. Since the first insect pheromone Bombykol, has been isolated and identified, more than 2,000 insect pheromones and their analogs have been identified and synthesized worldwide, of which more than 100 insect pheromone To achieve commercial production, the production and research of Lepidoptera sex pheromones is the most extensive and comprehensive.
