Method for root promotion and production increasing of continuous cropping sweet potato crops

Abstract

The present invention relates to a method for root promotion and production increasing of continuous cropping sweet potato crops. The method comprises the steps of: determining whether melon crops ina fruit swelling period or a mature period generate soil-borne diseases or not; and performing seedling dropping and stem burying processing for the melon crops with soil-borne diseases, and employingbacillus amyloliquefaciens or bacillus licheniformis and a rooting agent to perform root irrigation for newly buried plant stems to promote new root boost of the nodal plate portions so as to achievethe purpose of root promotion of the melon crops with soil-borne diseases. According to the method, about 8-15 days after seedling dropping and stem burying processing, the portion where the stem isnewly buried starts to generate white hair roots with absorption functions, and the plant water and fertilizer absorption function is greatly improved, at this time, plants do not need a sunshade netfor shading even at noon with much sunlight and can absorb enough nutrients for plant growth and swelling of fruits so as to ensure the normal maturing.

Description

technical field [0001] The invention relates to a method for promoting roots and increasing production of sweet melon crops in continuous cropping, and belongs to the technical field of agricultural cultivation. Background technique [0002] Watermelon and muskmelon are fruits that people generally like; they are also one of the most important economic crops with large planting area. However, if watermelons and melons are continuously cropped and cultivated for more than 3 years, diseases will increase significantly, and the yield and quality of watermelons and melons will decrease significantly. [0003] In 2016, my country's protected vegetable cultivation area exceeded 58.721 million mu, and it has now become the country with the largest protected gardening area in the world. Facility vegetables have become the most dynamic emerging industry in my country's agricultural production, and have played a huge role in the construction of my country's vegetable basket project. ...

Problems solved by technology

In addition to the increase in the number of continuous cropping pathogens is the main reason, the following physiological diseases are also aggravated year by year, which is also a reason for the aggravation of soil-borne diseases: such as: watering in the low temperature season in winter, watering before the cold snap; watering under the mulch in the high temperature season in summer It is easy to cause root retting; the concentration of chemical fertilizer applied is too high or the organic fertilizer is not mature. After being damaged, it is easily attacked by pathogenic bacteria in the soil and becomes soil-borne diseases such as root rot and wilt

Since the occurrence and spread of these diseases are in the underground, the plants are relatively small when they first occur, the fruit load is small or the fruit is relatively small, and the burden of the plant itself to consume and deliver nutrients to the fruit is small, so even if the root rot occurs At the beginning, the above-ground part cannot be seen; but when the fruit expands or matures, the external temperature rises, the evaporation in the facility shed increases, and the transpiration of the plant increases. In addition to the increased nutrient consumption of the plant itself, the expansion of the fruit A large amount of water and nutrients are needed for maturity and maturity. At this time, the burden on the root system is increased. The root system of the infected plant cannot meet the normal water and nutrient requirements of the plant, and the aboveground part gradually wilts.

The wilting plants or most of the roots have rotted, losing the best time for treatment, or the vascular bundles have turned brown and have been blocked. At this time, the root irrigation with medicine has little effect, and the fruits no longer swell and cannot mature normally, which seriously affects the crops. The yield and quality of the fruit, resulting in no commercial value

[0005] For example: In the spring of 2017, in Renfeng Town, an old watermelon planting area in Jiyang, Jinan, the whole shed of watermelon appeared to be wilting, the fruit did not expand, and the fruit shape was not correct. The watermelon that should have matured in more than 40 days still failed to reach maturity in more than 50 days To the mature standard, the taste is poor, and the loss of each shed is more than 10,000 yuan or even more

[0006] For the root rot caused by the above physiological damage or directly pathological root rot and root-knot nematode, it is difficult to be found in the early stage, and it will not appear until the fruit expands or matures, and the fruit no longer expands and cannot mature normally , there is currently no cure
