Disease-Resistant Nutrient and Research Method for incidence Thereof on Melon Quality
Technical Field The present invention relates to the field of agricultural planting, and in particular to a disease-resistant nutrient and a research method for the influence thereof on melon quality.
Background Melon is a cucurbitaceous trailing herbaceous plant and a famous specialty in Xinjiang, and has juicy and sweet fruit. Melon is one of the most widely grown economic crops in the world. The growth and development of melon need high temperature, dry air, abundant sunshine and temperature difference between day and night. Xinjiang, located in the hinterland of Eurasia, has a typical continental arid climate which is conducive to the growth and sugar accumulation of melon, especially in Jiashi County in Kashgar Prefecture which is the famous home of melon. However, many problems still exist in production of melon: 1. due to unreasonable management of soil and fertilizers in the production of melon, mineral nutrients in soil are in serious imbalance, which causes decline in the yield and quality of melon. 2. The inland region of Jiashi is dry and rainless and has high requirements for water and fertilizers, and the extensive irrigation technology cannot meet the requirements of large-scale production. 3. Natural disasters, especially albinism, freezing damage and insect pests, have serious influence on melon. The unreasonable use of chemical fertilizers directly causes the decline in the quality of melon products, and on the other hand, reduces the functions of melon to resist diseases and insect pests and prevent frost damage, which indirectly affects the yield and quality of melon as well as the control on the sustainable development of the melon industry.

NY1429-2010; (3) Disease-resistant nutrient: each 100 g of disease-resistant nutrient comprises 89.05 g of propamocarb, 6 g of iron, 3 g of zinc, 1 g of magnesium, 0.25 g of manganese, 0.2 g of boron and 0.5 g of humic acid; Experiment method: Dividing a melon field of 300 m 2 into three experimental plots, each of which has an area of about 100 m2 and is treated for three times. The first plot is treated as A (applied with the biological organic fertilizer), the second plot is treated as B (applied with the disease-resistant nutrient), and the third plot is treated as C (not fertilized). Preparation and sowing of the experimental plots: the experimental plots were prepared at the end of November 2015 and plowed in mid-March 2016, and melon seeds were sown formally on March 25, 2016. Fertilizing method for the experimental plots: applying the biological organic fertilizer to the first plot (respectively: 50 g/mu before flowering of melon, 100 g/mu during the fruit drop period, and 150 g/mu during the fruit determination period), and applying the disease-resistant nutrient to the second plot (respectively: 30 g/mu before flowering of melon, 50 g/mu during the fruit drop period, and 80 g/mu during the fruit determination period) by means of spraying, without fertilizing the third plot (ck). Determination method for melon morphological indexes: (1) Melon plants selected for observation in the experimental plots: nine melon seedlings growing normally are selected from each experimental plot, every three plants are used as one reiteration, the selected melon plants are tagged, the related indexes of the test are measured after the first fertilization, and the data are recorded; (2) Measurement of seedling length and flower number of melon: the seedling lengths of melon in the experimental plots are measured with a flexible rule after the first fertilization for a total of three times, respectively in the early, middle and late stages of melon growth and development, and the flower numbers are measured once when the melon plants flower to the maximum; (3) Fruit perimeter, fruit length and fruit number of melon: the fruit perimeters and fruit lengths of the melon fruits of nine selected plants are measured respectively with a straight rule in each experimental plot during the ripening period of melon; (4) Plant yield: when the melon fruits were ripe in July 2016, the melon fruits of nine plants were selected from each plot for measurement of fruit weight; (5) Data statistics and analysis: the test data are collated through Excel, and
CN109608253A Description Page 6/10
analysis of variance is performed by SPSS. Result analysis: (1) Influence of biological organic fertilizer and disease-resistant nutrient on melon morphological index: it can be known from Table 1 and Fig. 1 that the order of seedling lengths of melon from long to short in the three treatments is A treatment>B
treatment>CK, and the difference among the seedling lengths in different treatments
reaches a significant level (P<0.05). The biological organic fertilizer has a better
effect on promotion of the seedling length of melon than the disease-resistant nutrient and the control group. The flower number is one of the indexes that determine the melon yield. The variety with larger flower number and higher fertilization rate can achieve high yield. In this test, the flower number of melon in the experimental plot treated with the biological organic fertilizer is the largest, which is 33, the flower number of melon in the experimental plot treated with the disease-resistant nutrient is second, which is 32, and the flower number of melon in the control plot is the smallest, which is 28. The difference among the flower numbers in different treatments reaches a significant level (P<0.05). It is found in this test that the melon plants have
different fruit rates, each plant in the plot treated with the biological organic fertilizer has six fruits, each plant in the plot treated with the disease-resistant nutrient has six fruits, and each plant has five fruits in the control plot, which indicates that the biological organic fertilizer and the disease-resistant nutrient have obvious influence on the fruit rate of melon. Each plant is determined to have three fruits, but for a plant with more than three fruits, the fruits growing best can be selected during the fruit determination process. In this way, the yield and quality of melon can be improved.

and have shorter perimeters are more beautiful. The test result shows that the fruit perimeter of melon in the experimental plot treated with the biological organic fertilizer is the longest, which is 51.61 cm, the fruit perimeter of melon in the experimental plot treated with the disease-resistant nutrient is second, which is 49.21 cm, and the fruit perimeter of melon in the control plot is the shortest, which is 36.78 cm. The fruit perimeter of melon in the experimental plot treated with the biological organic fertilizer is the longest, which is 60.19 cm. The fruit perimeter of melon in the experimental plot treated with the disease-resistant nutrient is second, which is 57.13 cm, and the fruit perimeter of melon in the control plot is the shortest, which is 45.24 cm. The difference among the fruit perimeters and the fruit lengths of melon in
different treatments reaches a significant level (P<0.05).

(3) Influence of biological organic fertilizer and disease-resistant nutrient on melon yield: it can be known from Table 3 and Fig. 3 that the average melon weight is A treatment>B treatment>CK, the average melon weight of the experimental plot
treated with the biological organic fertilizer is 4.8 kg, the average melon weight of the experimental plot treated with the disease-resistant nutrient is 4.4 kg, and the average melon weight of the control plot is 2.6 kg. The plant yield of melons of the plots is A treatment>B treatment>CK, the average plant yield of the experimental plot treated
with the biological organic fertilizer is 14.4 kg, the average plant yield of the experimental plot treated with the disease-resistant nutrient is 13.2 kg, and the average plant yield of the control plot is 9.79 kg. The difference among the average melon weights and plant yields of melon in the experimental plots treated by different ways
reaches a significant level (P<0.05),which indicates that the biological organic
fertilizer and the disease-resistant nutrient have obvious influence on melon yield and can increase the melon weight and yield. Table 3 - Analysis of Variance of Influence of Biological Organic Fertilizer and

(4) Control of biological organic fertilizer and disease-resistant nutrient on incidence rate of melon: 30 representative plants are selected from each plot for observation of the growth period, and the incidence is recorded. The order of the incidence rates in three treatments is: CK>biological organic fertilizer>disease
resistant nutrient; and the rate of diseased plants of albinism of the blank plot is 66.7%, the rate of diseased plants of albinism of the plot sprayed with the biological organic fertilizer is 6.7%, and the rate of diseased plants of albinism of the plot sprayed with the disease-resistant nutrient is 3.3%, which indicates that the biological organic fertilizer and the disease-resistant nutrient have the function of controlling diseases in addition to increasing yield, wherein the disease-resistant nutrients has better disease resistance than the biological organic fertilizer, the biological organic fertilizer has the functions of increasing yield and resisting diseases in addition to improving the physical and chemical properties of soil, and the application of the biological organic fertilizer of the two fertilizers can achieve the purposes of improving the physical and chemical properties of soil and increasing yield.

When the biological organic fertilizer is sprayed for the first time (50 g/mu), the growth rate of
CN109608253A Description Page9/10
melon seedlings is very high after 4-5 days, the flower number also increases significantly, the melon seedlings are thick, long and green, and the fruit number is large; when an amino acid organic fertilizer is sprayed for the second time (100 g/mu), to increase the nutrient absorption of fruits, three fruits growing best are retained, and the other fruits are removed. At this time, the melon seedlings are thick and long, the fruits grow better and bigger, the weights increase obviously, the melon rind is nice, and the filaments increase; and when the amino acid organic fertilizer is sprayed for the third time (150 g/mu), the fruits keep growing bigger, and the weights increase. Since melons remain unchanged in late June to early July, flowers on the melon seedlings gradually decrease, and the nutrient is only provided for the fruits to promote the development of the fruits. At this time, the filaments continuously increase. The growth rate of the melon seedlings is high 45 days after the disease-resistant nutrient for melon is sprayed for the first time (30 g/mu), the flower number also increases significantly, the melon seedlings are thick, long and green, the fruit number is large, the leaves are also very large, and no symptom is found. When the disease resistant nutrient for melon is sprayed for the second time (50 g/mu), to increase the nutrient absorption of fruits, three fruits growing best are retained, and the other fruits are removed. At this time, the melon seedlings are thick and long, the fruits grow better and bigger, the weights increase obviously, the melon rind is nice, the filaments increase and become dense, and no symptom is found. When the disease-resistant nutrient for melon is sprayed for the third time (80 g/mu), the fruits keep growing bigger, and the weights increase, so flowers on the melon seedlings gradually decrease, and the nutrient is only provided for the fruits to promote the development of the fruits. At this time, the filaments continuously increase and become dense, and no symptom is found. The disease-resistant nutrient for melon promotes the nutrient absorption of melon, provides nutrients and has inhibitory and control effects on various diseases of melon to a certain degree. The plant yields of melon in the experimental plots treated with the biological organic fertilizer and the disease-resistant nutrient are respectively higher than that in the control plot by 47.09% and 34.83%; and the plant yield of melon in the experimental plot treated with the biological organic fertilizer is higher than that of the experimental plot treated with the disease-resistant nutrient by 9.09%, which indicates that the biological organic fertilizer and the disease-resistant nutrient can increase the
CN109608253A Description Page 10/10
melon yield. However, the biological organic fertilizer achieves better effects than the disease-resistant nutrient.
