A kind of vegetable transplanting film-laying machine
Technical field
The present invention relates to agricultural machinery technological field more particularly to a kind of vegetable transplanting film-laying machines.
Background technique
The advantages of using seedling transplanting technique: it first is that the crop growths such as vegetables can be made to shift to an earlier date, can be carried out using culturing and transplanting seedlings
Add stubble to cultivate or extend the planting season of secondary stubble vegetables, to increase yield and income;Second is that culturing and transplanting seedlings can alleviate seasonal crop rotation
Contradiction is conducive to interplant, raise the multiple-cropping index;Third is that show as root depth, robust seedling, stalk short for the crop after culturing and transplanting seedlings, and pass through
Directional transplant can make blade ordered arrangement, and uniform spatial distribution can utilize luminous energy;Fourth is that culturing and transplanting seedlings can subtract oligospermous use
Amount guarantees Miao Quan, full stand, reduces costs;Fifth is that can saving of labor province for removing weeds and seedling stage watering, fertilizing, insect pest preventing and controlling etc.
Power.
Northern Part of China, mean annual precipitation is 58.6 millimeters and temperature is lower, and plastic film mulch is carried out after culturing and transplanting seedlings,
It stamps the card on film again seedling mouth, the temperature inside soil can be improved, improve about 3-6 degrees centigrade.When to prevent being conducive to early spring
It waits, because night, temperature was low and cause the situation of root injury;Conducive to prevention waterlogging, if it is rainy day, then rainwater can be suitable
Mulch and flow to inside the ridge on both sides, being unlikely to rainwater all arrives in soil, causes rotten;Be conducive to nutrients inside soil
The storage of matter;Under large-scale plantation, artificial plastic film mulch expends a large amount of manpower and material resources, and laying of the membrane quality not can guarantee, and substantially reduce
Plantation efficiency;Mechanization film-laying machine is because its plastic film mulch is high-efficient, laying of the membrane quality is stablized, the welcome by wide farmers.
