Vegetable vegetable fertilization
Melon vegetables include cucumbers, pumpkins, melons, zucchini, bitter gourds and other cucurbits for harvesting young fruits or mature fruits as a type of vegetable. Melon vegetables can be divided into germination period, seedling period, flowering period and melon period. After entering the period of nectarine, the nutrient contention between growth and sturdiness is more prominent. It is necessary to pay attention to the supply of fertilizer to regulate the balance between plant growth and nutrient absorption and distribution. Melon vegetables are generally suitable for growth on fertile sandy soil or clay loam. Hi organic fertilizers are preferred. Therefore, deep-ripening and re-rotting organic fertilizers is the basis for growing strong vines and obtaining high yields. The nutritious soil of the melon vegetables requires loose texture, good air permeability, sufficient nutrients, and the pH is in the range of 5.5-7.2. The preparation method refers to the nutrition soil formula of the tomato. In the preparation of nutritious soil, the addition of 2% -3% of total superphosphate nutrient soil, to promote the growth of seedling roots, nurturing seedlings have a significant effect. Using nursery seedlings, when transplanted, mu with 2 kg of microbial inoculum after transplanting or rooting, can stimulate root growth, increase the survival rate of seedlings, and cultivate strong seedlings. Cucumber roots are mainly distributed in the 15-25 cm plough layer, and the salt tolerance is poor. It is not appropriate to use a large amount of chemical fertilizers at one time, while cucumbers require large amounts of nutrients such as nitrogen, phosphorus, and potassium, and the absorption rate is fast. Therefore, a large number of applications of bio-organic fertilizer is the basis of high-yield cultivation of cucumber, generally 80-120 kg of organic fertilizer applied in Mushi, with application of 4000-6000 kg of decomposed organic fertilizer as base fertilizer. The amount of fertilizer applied to the cucumber should not be too large, and the frequency of topdressing should be more, and the principle of “eat more meals less frequently†should be mastered. In the early stage of fruiting melon, the first top-dressing, Mushi urea 7-9 kg (12-15 kg of ammonium sulfate), with potassium sulfate 5-8 kg. In the early stage of the harvest, the second time, the interval between top dressings in the sorghum period is shortened and irrigation is carried out. For the third time before the top dressing, it will be halved after each time. During the fruiting period, it can be sprayed with 0.5% urea and 0.3%-0.5% potassium dihydrogen phosphate aqueous solution. Melon cultivation is divided into three kinds of cultivation methods: melon melon, greenhouse melon, and melon melon. The melon's root system is very developed and requires deep soil, so it is necessary to plow 25-35 centimeters deep. Before the site preparation, the basal fertilizer should be applied. Generally, 60-80 kg of bio-organic fertilizer is applied in Mushi, and 40-50 kg of superphosphate is applied, and then digging is performed according to cultivation methods. After planting, pour it with rotted manure water 2-3 times to promote its growth. When the fruit grows to the size of the fist, the fruit fertilizer is applied one time, and 10 to 15 kg of bio-organic fertilizer is applied to Mushi and 5 kg of urea is applied. When the first batch of melons was harvested and the second batch of melons were applied, 15-20 kg of bio-organic fertilizer was applied. The roots of pumpkins are well-developed and their soil quality is not strict. However, they have a long growing period and are hi-fertilizer and must be cultivated deeply. Before the seeding, the pumpkin was fertilized and 60-80 kg of organic fertilizer was applied. The pumpkin has a long growth period, high yield and consumes more nutrients. In addition to the base fertilizer, it should also be top-dressed in stages. The topdressing is applied in the early stage of growth; the results are reapplied. During the seedling stage, the main body of the seedlings was poured with cooked water, preventing leggy and affecting the fruit setting; the result was that 0.5 kg of bio-organic fertilizer was applied to the post-cultivation acupoints to promote fruit hypertrophy. Bitter gourd is a one-year-old climbing herb with a more developed root system and more lateral roots. Bitter gourd was used as a base fertilizer before planting. General Mushi biological organic fertilizer 60-80 kilograms, spread or ridge after spreading. Bitter gourd has a long growth period and many female flowers. It can continuously produce melons with long harvest time, consume large amount of fertilizer, and timely top-dressing to supplement nutrients. After the flowering results, the combination of watering every 15-20 days to recover 1 fertilizer, the amount of fertilizer is 10-15 kg of mu for urea. The result should be increased by one superphosphate, prolong the harvest period, increase the yield, and improve the quality. Excerpted from China Agricultural Press>
