Problems solved by technology

[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 fertilizer

Embodiment 1

[0020] The impact of different treatments of embodiment 1 on the amount of pathogenic Fusarium oxysporum in soil

[0021] The experiment was carried out in July 2017 in a vegetable greenhouse in Nanjing Vegetable Science and Technology Park. The soil has been planted with melons for 3 consecutive years, and the soil has already experienced obvious continuous cropping obstacles. The basic soil nutrient index content is: organic matter content 16.56g·kg -1 , available potassium content 254.03mg·kg -1 , available phosphorus content 12.68mg·kg -1 , alkaline hydrolysis nitrogen content 1.54mg·kg -1 , pH is 6.55, EC value is 148.4μs cm -1 . Three different treatments were set up (see Table 1 for specific treatments), and each treatment was repeated 3 times.

[0022] The specific operation steps of the stuffy shed are as follows: (1) Cleaning the greenhouse: after the vegetables and other crops are harvested, the shed film should not be uncovered immediately, but the loopholes s...

Embodiment 2

[0027]After the facility melon is processed according to the method in embodiment 1, plant melon (No. 5 Yongtian), each plot planted 13 muskmelons (community area 2m * 5m), and counted the dead quantity of each processing muskmelon seedling, concrete result is as follows As shown in Table 2, it can be seen from the table that when lime nitrogen and quicklime were applied, the dead trees of melon showed a clear downward trend compared with T1 treatment, and the mortality of melon decreased by about 13% compared with T1.

Embodiment 3

[0031] The influence of embodiment 3 different sterilization methods and fertilizers on muskmelon yield

[0032] The inventive method (T4) comprises the following steps:

[0033] (1) During the fallow period in the facility greenhouse, sprinkle lime nitrogen and quicklime into the soil where the melons are planted, and the dosages are: 50 kg / 667m 2 and 50kg / 667m 2 , then plowing, leveling, sealing the greenhouse and watering (making the soil moisture reach more than 90% of the maximum water holding capacity), covering the soil with a white film after watering, so that the temperature of the greenhouse reaches 55-60 degrees Celsius, 25 days of stuffy shed treatment;

[0034] (2) After the stuffy shed is over, remove the plastic film, ventilate the shed for 5 days, then plow it, and ventilate it for 8-10 days (to make the lime nitrogen in the soil volatilize completely), and then spread bio-organic fertilizer 400kg / 667m 2 , compound fertilizer (15-15-15) 17.5 kg / 667m 2 , an...

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, ...
