Pre-preparation of locust culture:
1, selection of land: see the scale, see the soil, see the terrain, see the topography, site preparation
(1) Scale: After determining the scale of breeding, rationally use the land to achieve a reasonable ratio of breeding and planting;
(2) Look at the soil quality: The culture of East Asian cornicidal planthoppers does not require high soil conditions. In order to absorb water well and have low viscosity, it is better not to accumulate soil.
(3) Look at the terrain: regular, concentrated, topography: formation, high ground
The general requirement is that land consolidation is not fragmented, and the topography of the farming area must be high and easy to drain.
The specific choice of terrain: the land must be high in terrain, drainage is clear, light is suitable, low-lying terrain is prevented, summer rain is too large, and soaking eggs or nymphs, causing unnecessary losses.
The ground must be flat, the pH is not too high, there is no weed, try to compact the land as well, this will play a big role in the number of eggs laid by the locusts. In order to facilitate the drainage of the rainy season, the soil is best to use sand. Soil, this soil is not easy to agglomerate, easy to produce quail eggs.
(4) Look at the environment: Long time of light, no pollution, no noise, complete water and electricity facilities, convenient transportation, and rich forage resources nearby.
Lighting: strong lighting, long sunshine hours;
Pollution: Pesticide source, chemical plant, far away from 500 meters, away from roads, railways, 500 meters above;
The management of natural enemies: birds, rodents, frogs, etc., as well as crickets, ants, spiders, etc.
Hydropower: easy to drain, easy irrigation, 220V voltage;
Transportation: easy to transport forage, easy for adult recovery and transportation;
Peripheral crops: far away from sprayed pesticide crops, rich in grasshoppers;
(5) Land preparation: The objective is that the topography of the culture area is higher than that of the planting area. The planting area is easy to be irrigated and drained, which is conducive to breeding and planting.
In the shed: The ground in the shed is flat and grassless, and the height of the shed is 10cm.
Outside the shed: The land is flat, easy to be irrigated, easy to drain, reserved for lanes;
Ground treatment: Before constructing the shed, conduct comprehensive treatment of underground pests (such as cockroaches, spiders, ants, etc.) to avoid the growth and breeding of such pests in the shed. The specific prevention methods are as follows:
1. Take advantage of the light, combined with the large water bottle filling method to capture artificially, and irrigate detergent water with high concentration into the cave;
2, for ants: a physical method can be used: boiling hot; one can use trapping (sweet trapping)
3. For birds, etc., we can observe and push forward.
2. After a reasonable allocation of land, we first plant forage grass, which can ensure sufficient forage. Specific steps of planting forage:
(1) Planning and planting: climate characteristics: surface temperature is above 15 degrees;
Dry and wet soil: water content above 20%;
Water source assurance: irrigation facilities such as ditch wells;
The number of sheds: the number of sheds needed to establish and improve;
Planting area: Gradient planting techniques (meaning: forage grasses at each plot, gradually wrong after planting time).
(2) Technology for growing forage grass:
Types of forage: East Asian cornfieldworms have a wide range of feeding habits, such as grasshoppers, such as reed grass, rice, corn, wheat, Mexican corn grass, etc., and they can be planted in large scale. For more groundgrass forages, select reusable varieties to increase economic efficiency.
(3) Points to note when planting forage grass:
In the process of seed selection, we must select second-generation seeds, which are full of particles and have good varieties without pesticide coating. In the shed where seedlings have not yet been planted, wheat can be planted in advance, and when the temperature is adjusted, seedlings can be input. In the greenhouse, forages throughout the shed can be eaten by larvae for about 7-10 days (depending on the density of forage grass in the shed). This reduces the number of culturists entering the shed, that is, saving manpower and saving time. Reduce relative losses.
3, build a shed: We build a shed in two sizes, one is the general shed covers an area of ​​102 square meters, 6.8 meters X15 meters, there is a kind of standard base shed, covers an area of ​​204 square meters, 6.8 meters X30 meters;
(1) Materials required for the construction of the shed: According to the standard shed construction shed design, the company provides materials for building sheds in a unified way, using 6 points thick galvanized pipe length of 0.5 meters (thickness 1.3-1.8mm) 22, 0.3 meters 11 , 4 points thick galvanized pipe length 3 meters (wall thickness 1.3-1.8mm) 11 with, 6 meters 11 with, nylon gauze net and buckle shed labor costs, a total of 2400 yuan / shed (can be used for 3 to 5 years).
(2) Basic steps for building a shed:
1. Determine the size of the shed 30 meters long, 6.8 meters wide, (take a 50 meters tape measure), determine the direction, the shed spacing is 1 meter, the distance between the feet is 3 meters, and the 50cm floor cleaver is flatly inserted into the ground 5cm, take a sledgehammer , valve, 1 person to support the ground, the foot tilted inward 75 degrees, 1 person with a sledgehammer to the ground exposed to the ground 5cm, with 30cm connecting pipe 2 and 4.5 meters galvanized pipe connected, the two will be connected At the same time, insert the symmetrical height of the two ends and adjust the uniform height of the skeleton. Close the groove around the outside of the foot and dig the groove of the buried gauze that is 35cm deep and 20cm wide. Place the digging soil on the outside of the shed and find the door. The net will be spread out, the positive and negative sides will be determined, the net will be pulled up, the net will be compacted, and the nets will be adjusted.
2. Backfilling: compact the net to ensure that there is no gap between the inside and outside of the shed. The ground in the shed is flat and grassless, and the height of the shed is 10cm. When backfilling, pay attention to the tightness of the zipper at the shed.
3, digging drainage ditch: 50cm outside the shed to dig deep 25cm wide and 20cm long drainage ditch with the shed, and connected with the main road drainage ditch, the shed's two still use the top of the bamboo raft.
4, the management of natural enemies: ants: sweets trapping, boiling water hot; spiders: artificial capture; è¼è›„ ç¯: light, concentrated washing powder water irrigation; frogs: artificial capture; birds: network capture.
(3) For seedlings: After all preparations have been completed, we begin seeding seedlings in the shed.
The standard of seedlings: Varieties: Purebred East Asian corniculturist, living limbs die.
Quantity: According to the size of the farmer, weigh it, and use a reasonable method to weigh it out. Calculate the quantity.

Natural pigments are food pigments obtained from natural resources. Pigments extracted mainly from animal and plant tissues and microorganisms (cultures), in which vegetative colorants predominate. Natural pigments not only have the function of coloring food, but also have physiological activity. At present, there are 48 kinds of edible natural pigments approved to be used in China, commonly used chili red, beet red, monascus red, cochineal red, gaolianghong, sodium copper chlorophyllin, turmeric, gardenia yellow, carotene, algal blue pigment, cocoa pigment, caramel pigment and so on.
