Abstract
The invention discloses a method for planting transplanted watermelon seedlings in an old gravel-mulched field. The method comprises the following steps: cultivating watermelon seedlings in a seedling tray in a greenhouse; when 3-4 true leaves emerge, transplanting the watermelon seedlings and a nutritive matrix to the old gravel-mulched field; after the transplantation, irrigating with about 1 L of water, and covering the field with a mulching film; after the watermelon seedlings turns green from yellow and vine grows, tying a 2-3cm hole on the mulching film for ventilation; along with the gradual growth of the watermelon seedlings, expanding the hole until the watermelon vine grows to 15-20 cm; completely releasing the watermelon seedlings from the mulching film; and after the watermelon seedlings are released from the mulching film, dissolving ternary compound fertilizers in water and directly irrigating the roots with the dissolved fertilizer in the vine extending period and flowering period respectively, wherein the irrigation is performed 3-4 times in the watermelon childbearing period, and 5-6 m<3>/mu of field is irrigated each time. The method is easy to operate, ensures high survival rate of watermelon seedlings, short rejuvenation period, fast growth, strong disease resistance and high watermelon yield, and is especially suitable for the old gravel-mulched field with low soil fertility and serious continuous cropping obstacles of the middle dry zone in Ningxia.
Description
Technical field
Patent of the present invention relates to a kind of old pressure sandy ground watermelon transplanted seedling kind method for planting.
Background technology
The existing long history of plantation watermelon presses sand to have the evaporation of minimizing on the arid zone pressure sandy ground of middle part, Ningxia, keeps the effect of soil moisture content, and therefore, the plantation of pressure sand is the planting patterns in a kind of suitable drought and water shortage area.Press the quality of watermelon of planting on the sandy ground good, remarkable in economical benefits, cultivated area constantly enlarges.But owing to press sandy ground farming, fertilising and crop rotation difficulty, along with the increase of the plantation time limit, soil fertility constantly descends; The continuous cropping obstacle aggravation; The poor growth of watermelon, the incidence of disease high (the most serious) with fusarium wilt, output reduces; Economic benefit descends, and this directly influences the sustainable development that middle part, Ningxia arid zone is pressed sandy ground watermelon industry.
Tradition is pressed on the sandy ground, and the method for plantation watermelon is to choose full seed, through insulation vernalization, treats that bud is long just can plant in the field to 2-3cm.But, utilize the watermelon growing of this method plantation slow, morbidity easily at the old sandy ground of pressing.Therefore, need to seek a kind of suiting in the old method of planting watermelon on the sandy ground of pressing, to improve the output and the disease resistance of watermelon.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to prior art; A kind of old pressure sandy ground (to press sandy ground always be the finger pressure sand plantation time limit greater than 20 years pressure sandy ground) watermelon transplanted seedling kind method for planting is provided; Can improve the survival rate of watermelon seedling, disease resistance and The yield of watermelon.
The present invention adopts and takes off technical scheme:
A kind of old pressure sandy ground watermelon transplanted seedling kind method for planting is characterized in that, may further comprise the steps; When in the greenhouse, cultivating the watermelon seedling to 3-4 sheet true leaf, the melon seedling (for avoiding injuring melon shoot root system, is with nutrient matrix together with nutrient matrix during the melon transplantation of seedlings with seedling-cultivating tray; For example the main component of nutrient matrix is vermiculite and peat; For watermelon shakes down buffering is provided like this,, thereby has helped slow seedling simultaneously for the watermelon root soil provides organic materials) transplant together on old pressure sandy ground; Transplant the every strain in back pour water 1L, covering with plastic film then; Treat that the watermelon seedling is green by xanthochromia, grow melon when climing, the hole of on mulch film, pricking a 2-3cm is used for ventilation and leaks informaton; Along with the watermelon seedling is grown up gradually constantly the hole is amplified, to melon is climing grow to 15-20cm after, the melon seedling is emitted from mulch film fully; Directly irritate NPK is water-soluble stretching climing phase and flowering stage respectively in root.
Described old pressure sandy ground watermelon transplanted seedling kind method for planting, watermelon irrigation in growing period 3-4 time, each 5-6m
3/ mu.
Described old pressure sandy ground watermelon transplanted seedling kind method for planting, said NPK is: N: P
2O
5: K
2O=15: 16: 14.
Described old pressure sandy ground watermelon transplanted seedling kind method for planting, said NPK consumption is a 5kg/ mu.
Adopt method of the present invention, significantly improved survival rate, disease resistance and the The yield of watermelon of watermelon seedling.
Embodiment
Below in conjunction with specific embodiment, the present invention is elaborated.
Embodiment 1
When in the greenhouse, cultivating the watermelon seedling to 3-4 sheet true leaf, the melon seedling (for avoiding injuring melon shoot root system, is with nutrient matrix together with nutrient matrix during the melon transplantation of seedlings with seedling-cultivating tray; For example the main component of nutrient matrix is vermiculite and peat; For watermelon shakes down buffering is provided like this,, thereby has helped slow seedling simultaneously for the watermelon root soil provides organic materials) transplant together on old pressure sandy ground; Transplant the every strain in back pour water 1L, covering with plastic film then; Treat that the watermelon seedling is green by xanthochromia, grow melon when climing, the hole of on mulch film, pricking a 2-3cm is used for ventilation and leaks informaton; Along with the watermelon seedling is grown up gradually constantly the hole is amplified, to melon is climing grow to 15-20cm after, the melon seedling is emitted from mulch film fully; Directly irritate NPK is water-soluble stretching climing phase and flowering stage respectively in root.
Described old pressure sandy ground watermelon transplanted seedling kind method for planting, watermelon irrigation in growing period 3-4 time, each 5-6m
3/ mu.
The watermelon seedling survival rate of this method plantation reaches 99.5%, and in the fusarium wilt high-incidence season, about 13%, and the incidence of disease of transplanted seedling is merely 4～5% with the incidence of disease of the live watermelon bud of plot; Harvest time, the watermelon average yield of live watermelon bud was a 1122kg/ mu, and the watermelon average yield of transplanted seedling is a 1421kg/ mu, and output has improved 26.6%.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
