Preventing and treating method of muskmelon successive cropping obstacle

Abstract

The invention discloses a preventing and treating method of a muskmelon successive cropping obstacle. The method includes the following steps of firstly, scattering lime nitrogen and quick lime in soil in the fallow period of a facility greenhouse, conducting turning, leveling and greenhouse sealing and watering, and covering the soil with a white thin film after watering for greenhouse suffocating treatment; secondly, removing the plastic thin film after greenhouse suffocating ends, conducting turning and ventilating treatment after the greenhouse ventilating treatment, scattering a biological organic fertilizer and a compound fertilizer, conducting rotary tillage, even mixing, ridging and black film covering, planting cultivated muskmelon seedlings in the soil, and spraying an amino acidleaf surface fertilizer on muskmelons once every 8-12 days. By means of the method, the soil is disinfected in the early period, and the muskmelon successive cropping obstacle is reduced; by applyingthe biological organic fertilizer, the physical and chemical properties of the soil are improved, the consumption of the chemical fertilizer is reduced, meanwhile the content of organic matter in thesoil is increased, the microorganism flora of the muskmelon planting soil is reconstructed, crop growth and nutrient absorption are facilitated, and on the other end, by means of the biological organic fertilizer and the amino acid leaf surface fertilizer, the muskmelon yield can be ensured and the muskmelon quality can be improved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a method for preventing and treating continuous cropping obstacles of melons. Background technique [0002] Continuous cropping obstacle refers to the cultivation or planting of the same or related crops on the same soil, even under the normal field cultivation management mode, it will cause the phenomenon of weakened crop growth, reduced yield and quality. At present, the control methods for continuous cropping obstacles of protected muskmelon are mainly divided into: crop rotation, soil adjustment, grafted seedlings, chemical control, biological control and other control methods. There are certain disadvantages in the existing control methods. For example, the chemical control method mainly uses chemical substances in the soil to sterilize the soil, so as to achieve an effective method of inhibiting soil-borne diseases. Often during the disinfection process, ...

[0003] In addition, there are many factors that cause barriers to continuous cropping in facility soil. Among them, excessive use of chemical fertilizers is one of the main reasons for this phenomenon. Excessive application of chemical fertilizers leads to soil acidification and nutrient imbalance. The main manifestations are: relatively single types of facility cultivated vegetables, Farmers often apply a large amount of fertilizers with the same or similar properties continuously according to traditional habits, coupled with the selective absorption of fertilizers by crops, so that some nutrients in the soil decrease sharply, while other nutrients gradually accumulate, resulting in soil nutrient imbalance

According to the policy guideline of “Double Reduction of Pesticides and Chemical Fertilizers” put forward by the Ministry of Agriculture in 2015, reducing the amount of chemical fertilizer used in the planting of protected vegetables is one of the effective methods to prevent and control soil continuous cropping obstacles, but if simply reducing the amount of chemical fertilizer used is can significantly reduce crop yields
