Pest-control and freezing-preventive cultivation method for water dropwort growth

Abstract

The present invention relates to an insect-proofing and antifrost cultivation method in growth stage of water dropwort. It is characterized by that several piles are uniformly set around the ridged field in which the water dropwort is planted, the top portions of piles and periphery of said ridged field are covered with sun-shading screen, its sun-shading rate is 50-65%, and said ridged field is completely closed.

Description

technical field [0001] The invention relates to a method for cultivating cress, in particular to a method for preventing insects and freezing during the growth of cress. Background technique [0002] Aquatic vegetable cress is generally sown in August to September every year. At this time, the temperature is higher and there are more pests. Since cress has been in the field for 7 months, it will encounter cold seasons. At this time, cress is very easy to grow. Frozen. [0003] Before the present invention, when watercress grows in high temperature, in order to solve the impact of insect pests on watercress growth, pesticides are generally used, and a little carelessness when using pesticides will inevitably lead to the residual pesticides on watercress exceeding the prescribed safety Standards are not conducive to the hygiene and safety of vegetables. In order to prevent freezing damage in cold seasons, deep water irrigation is generally used to prevent freezing and soften...

Problems solved by technology

This method of cultivating cress requires a lot of water, and China is a country with serious shortage of water resources. Even in the south, this method is not conducive to agricultural water conservation, let alone in the north where water is scarce; a few areas use deep The method of burying plants is anti-freezing, but it greatly increases labor costs, and the requirements for soil are very high. Generally, it needs to be planted in silt fields, and conventional soil cannot be operated; There are many processing procedures, resulting in high labor intensity, time-consuming and labor-intensive harvesting, and increased harvesting costs; in addition, due to the need to dig ponds or build high ridges, once it is necessary to switch to planting other plants, it is very inconvenient and not conducive to the replacement of planting types and adjustment, so this cultivation method does not conform to China's national conditions, and it is difficult to promote and implement it on a large scale
